Übergame is a free open source, realism like, multi-purpose, multiplayer, casual, first-person-shooter game.
Story:
The game itself has no fixed storyline, only that it is supposed to become a free open source replacement for common multiplayer shooters, from basic deathmatch like quake over to team based games like counter-strike. It will be more like a sandbox that tries to combine a bunch of similar genres.
Sure commercial games can also be modded, I did so also in the past, but it was very frustrating, since it was always a dead-end. You did not own the engine or the content you modded and so you never had the rights on your creation and when the next version of the engine or game came out, you would lose all your playerbase, since they will move on to the new game, so if you would want to keep up you would have to buy the new game and start from scratch modding it again. So modding always turned out to be a waste of time, but I want to change that, by keeping everything on the same platform, to keep it compatible and free.
