I love the Battle in this game, to the point where I would like a Endless attack mode: You Choose an Aircraft, game gives ONE enemy, after you defeat the enemy, you receive a option to repair your aircraft, or reload one weapon.
This repeats multiple times. Soon the game gives out TWO enemies, the enemies also get stronger progressively.

Also to make the ENEMY'S correctly matched to the Players, allow the player to choose what types of enemies they want (Land, Air, Sea.) What engine types and arrangement (Single Jet, twin Jet, Single Prop, Twin Prop, Etc.(For Air))
And the option for the enemy's armament (Flak, AA Gun, SAM (For Boats and land) and Missile and Guns (For Aircraft)) and even an option to select what specific Aircraft they want to fight. The Defaults for these options would be: Targets: Air, Engine: Single Prop, Weapons: Guns.
Thanks for reading.
