Ok, get into the cockpit with XRacer or GlRacer . You see, it's all out there. Most of the games provide, as they run under Linux, multilayer capabilities, which makes things even more exciting. Maybe you already know some of the games, while others are totally new to you. There are clones and ports of existing PC games as well as new games of known genres.
Ports usually behave exactly as the original game.
Well, at this point it's time to lower expectations a bit. There are a lot of game projects out there. They all differ if it comes to graphics and gaming quality. Some are complex, some are simple, they are all under constant development, maybe already playable, maybe not yet. So don't expect to be happy with all of them.
