The map is terrible
It needs to be fixed
1. Make the land more realistic. Mountains should not be that steep.
2. Add more roads. The current ones are bad and there are too few. Add some railways.
3. Make the land more vehicle friendly. You get stuck too easily
4. Fix the airports. Make them more realistic with normal taxiways, gates, ramps, helipads. Fix. the. stupid. curbs. on. Yeager.
5. Stop the snowstone missile launchers from shooting at you while you are trying to drive on the ground
6. Add more trees and buildings.(Or a setting to).
7. Add a city area, woodland, plains, etc
8. Have more land rather than some tiny islands in an infinite ocean
9. Connect the islands more. Make them larger, put them closer, and/or add bridges.
10. Add some more ports for ships.
11. Make the tiny unnamed islands bigger.
I think that's about it.

These are the current rules:
No sexually suggestive content or foul language
You are not the first person to make a penis-shaped airplane. The joke is old and boring now.
We are not going to moderate every curse word, but please try to keep it clean.

Don't abuse the voting system
Don't tell someone: 'If you upvote my stuff, then I'll upvote your stuff.'
Don't make alternate accounts to upvote your own stuff.
Don't beg other users to upvote your stuff.
Don't cancel challenges that have successor points.

Regarding Posts
Don't post the same thing multiple times.
No more than 3 public airplane submissions per day. No more than 10 unlisted submissions per day.
No sympathy posts or memorial posts. Move those discussions to the forums.
We allow a wide variety of uploads that are not actually airplanes. However, we do reserve the right to remove posts if they are too far off-topic.
Don't spam other players' posts with links to your stuff.
Don't use offensive symbols, unless they are necessary for historical accuracy (ie - Swastikas should only be used on things like a WW2 German Bomber).
While we allow photoshoped thumbnails, post with misleading thumbnails will be removed.

Don't abuse the post reporting system.

Politics and Religion
Please, remember that this is a game about airplanes. While we do allow off-topic conversations in the forums, if you talk about religion or politics then there is a good chance that your post will be removed. Especially if we feel that it is likely to stir up debate.

Be kind
Be friendly to new players!
If you are continually telling people their airplanes suck, then maybe you suck.
No hate speech. You will be banned immediately.
Please, just be courteous.

Blocking players is okay
It is every player’s right to block whomever they wish for whatever reasons they wish.
Being blocked by a user in no way hampers your ability to enjoy the game or this website. If someone blocks you, be a better person and simply move on.
If you retaliate in response to being blocked, then you will be banned. Do not post or comment about a player who blocked you, about a specific player who blocked a friend of yours, or about a specific incident about specific people involved in blocking one another.

Tweaking airplanes is okay
It is okay to download someone else's airplane, make some tweaks, and re-upload a new variation.
In fact, the original designer may even receive bonus points.
However, if your variation does not offer any improvements over the existing airplane, then it may be removed.
If you are circumventing the predecessor/successor system, then you will be banned. Never upload a successor as an original design; give credit to the designer of its predecessor.

Naming your airplanes
Don't name your airplanes for a YouTuber. Instead, give it a cool name and use the tag system. It looks less spammy and the tag system makes it easier for YouTubers to find cool planes.
Example of a bad name: JELLY CHECK THIS PLANE OUT! [No Tags]
Example of a good name: F55 Super Dasher [YouTuber-Jelly]
Be courteous if you find a violation of this rule. New players may not be aware, so just link them to the rules and tag a moderator.

If I may, I'd like to propose some additional amendments to these rules. First, they tend to be quite vague. For instance, "Be kind" or "Be courteous" are somewhat open ended. While I know basically what this entails, I know there are people with significantly less common sense that would either try to bend the rules or just ignore them completely and think that telling people their planes are bad is being kind. Secondly, I think there should be a rule about repeated offenders. From what I've observed, someone who has broken a rule is much more likely to be punished for something minor in the future. This should be spelled out in the rules. Maybe make a link to Andrew's "Where do you stand?" forum in there. Third, the punishments are vague. While some violations like hate speech, thumbnails, off-topic things, politics and religion, and circumventing the successor system have spelled out consequences, others do not. This causes players to question moderator decisions as they do not believe those violations are enough for them to be banned, striked, etc. And in the interest of limiting the questioning of moderator decisions I know this would be a smart choice. Fourth, I have a couple new rules to suggest. Those rules are as follows:
1. No intentional starting of drama. While the question of intent is usually the reason people get banned or striked, I think we should outline it more clearly to warn people. Add examples of starting drama such as making a forum calling out a particular user/users or questioning moderator decisions regarding banned players. Nowhere in the rules is the word "drama" even mentioned, so in essence this rule is being enforced without being a rule. A "phantom rule", if you will.
2. A truth rule. If someone does call out a user for being a jerk to other people, they should not be penalized. While I agree the forum should be removed to avoid drama, if someone is posting pictures of their comments that harass users, then that is not slander nor libel (It would never be slander because slander is verbal). Since unedited pictures would not be false, it should be accepted as reporting. If it is found that they either used the report button with no effect or did not know how to utilize the report button on comments or posts, then there should be no punishment, just a warning to report it on an unlisted post next time.
Sometimes, what was a good intent turns into a ban or strike because someone was trying to report something they felt the moderators had been annoying for some time. While this may not be true, we can't discount their efforts to bring someone to justice. I like the new strike removal policy, and I hope that when the rules are revised to add that policy and the third party harassment rule that these suggestions are taken seriously.

SimplePlanes is a simulation game, which is great because you can build whatever you want and then expect it to fly exactly like it would in real life!

Not exactly...

One massive thing is stopping any aircraft's flight dynamics dead in its tracks: drag.

SimplePlanes drag model in its current state is so bad in fact, that I recently had to cut my aircraft's drag by almost 98% and that only got it close to flying properly. Engines need to be more powerful to make adequate thrust (which really messes with takeoff performance) and when you send your power to idle at 10,000 feet it feels like you just ran into a wall with how fast your plane decelerates, and you need to enter a vertical nosedive to gain speed again.

THIS IS NOT REALISTIC!!!

This is why the drag model needs a total overhaul. Airplanes simply need to make less drag than they currently do in SimplePlanes. As in, 98% less drag. This will allow for some awesome stuff like better gliders and more efficient engines, as well as much better thrust physics.

Also, instead of focusing on individual parts, I suggest that the drag model looks at the plane as a whole and figures out how much air resistance the entire shape will create. Do away with the drag points system and instead use a Drag Coefficient to determine how much drag your airplane will create.

Implementing both of these things would help the flying part of the game a lot, and would help builders like me improve realism as much as possible on our builds. Thank you for your consideration.

Suggestion 1: Fuselage "Twist" Property:

In the fuselage editing box there would be a new slider below the fuselage block size and corner selectors, that when moved would twist one end of the fuselage. You can twist left/right sides or front/back. Range from -360 to 360 degrees. Maybe a little button above the slider as well to choose which side to twist. This would make complex shapes an absolute breeze in the game, such as wings and stuff.

Suggestion #2, Left/Right Scaling:

Allows you to change the size of the left and right sides along with the front and back. Again, more possibilities with complex shapes.

The people of SimplePlanes (mainly IOS users) are being stricken of their ability to succeed in an increasingly competitive field of play. Many users are unable to provide the flashy screenshots that PC and Android users are able to. I myself have resorted to using my PC to upload my builds, since I can upload it with screenshots. However, it is essential that we make it easier for IOS users to receive the recognition they deserve. We should also include an option to remove the UI on mobile devices in order to take better screenshots, or install a screenshot button that takes a shot without the UI in the way.

Reason 1: Fairness
In order to level the playing field and give everyone an equal opportunity, we must allow them to provide their best screenshots like all other users.

Reason 2: Attraction
People will be more likely to be attracted to the game if they are able to find success, as all humans, whether they like it or not, are looking for the validation of upvotes and comments on their work. Attractive screenshots mean more popularity, therefore new users are more likely to recommend SP to a friend.

Reason 3: It's just cool
Screenshots are fun. Being able to select a picture from your camera roll and inserting it is a proper showcase of a build you may have spend ages working on, and editing the screenshot itself is just as demanding.

Conclusion
This is why we must provide the same screenshotting opportunities to mobile devices as we do PC players. We don't absolutely need frecam or zoom, but it would be nice to make screenshots look their best. We do, however, need to be able to upload our own screenshots, and take good-quality ones without having to crop the UI out.
