Cannot decide between
Quake and not just for OpenGL but first death match too
Unreal for jaw dropping effects (even if polygon count was too high at times)
Deus Ex (level design 2nd to none but another game where polygon count was too high for suggested hardware)
GTA yes the first one
Half-life for its exceptional attention to detail
But half-life 2 wins for me mostly thanks to physics which changed games forever
