Does linux have a graphical thing (like DirectX), that can run games... why dont we people (we being a whole group of people), make a game... that uses a program like DirectX to run its graphics... a game, like HL, or simular...

Where someone makes the map editors and the files needed to run the game, and then some other people make the multiplayer maps and all sorts of things like characters and objects (like a box or computer). And someone do the textures.

So! Who wants to make a game... i have some game ideas and some game scripts (story lines for a game). anyone with me... or am i alone...
