I remeber immersing myself into the worlds or DOOM...
Don't knock DOOM's graphics either. For it's time it was absolutely mind-blowing. The combination of texture mapped 3D environments, intricately hand drawn 2D sprites, and the moody 256 color pallete was something no one else could pull off for quite some time.
It's been a long while, but I think we're on the verge of another revolution on that scale.
Back on topic, I'd play TRON 2.0 for the visual style ALONE.
