I think this game could really use some incentives to donate. While this game (due to the fact that most of its content is copywrited) cannot be used commercially, you can offer 'gifts' for donating. The 'gifts' could be something thats usually able to be found ingame, or maybe even something that isnt (such as power armour or gauss rifles, though i like the game without them). but more importantly, it could involve things like respawning mercs/items, or guns that dont deteriorate. not stuff that would make a person unkillable, but things that would make things a bit easier, or make it quicker for a person to get back on their feet when killed.
so come on people, things you like, dont like, additions, revisions even hate mail is appreciated
