Due to overtime at work, I haven't had time to play games as such (had to miss the LAN party too), but while waiting for compiles and such did put in a few minutes to get some games running on Linux, and to sample some Xbox 360 content I downloaded.
The games now working in Linux, either through Crossover Games, DosBox, or Scummvm are: Sacrifice, Lure of the Temptress, X-COM: Apocalypse, X-COM: Interceptor, X-COM: Enforcer, and Half-Life 2. Team Fortress 2 still won't run, and I've run out of things to try. The others I'll put more time into when I have free time again in my schedule.
Xbox Live content I sampled includes Exit 2, Fallout 3: Operation Anchorage, Grand Theft Auto IV: The Lost and The Damned, Tomb Raider Underworld: Beneath the Ashes, and Groov. I'll be spending more time with these when I have more time to spend.
