What have been your favorite games?
Arcade Types- Foresaken, Quake2, and Unreal Torurnament
Driving Simulators- Grand Prix Legends- very dated, but still tons of free tracks of just about everything. In second place would be NFS Porche Unlimited(not really a true sim though).
The new GTR2 looks exceptional.
Flight Simulators- IL2 series definitly. In second was IAF but it was pretty buggy.
FPS- Operation Flashpoint Resistance definitly. The first to combind massive non-linear environments, 1-shot kills, interactive vehicles, and tons of free mods. The Rainbow6 and Ghost Recons were fun but quickly got boring.
The next version of OFP is called Armed Assault is is in the process of being released. A screenshot :
