SR2 gameplay and graphics are already pretty impressive, but there's currently nothing in the game that gives it any character or personality. It feels very... generic.

It would be great to see some things that add some life and unique personality to the game (like the Kerbals and Kerbal culture do in KSP, though obviously you should do something original). You don't have to go overboard with it, just something to give the game a little flavor and character.
