Graphics? I can handle anything 2D and most 3D games beyond 2000. Those early 3D titles are playable but hurt my eyes.

Gameplay? Anything that doesn't feel very clunky and has a map of some kind for more open areas. Old games like to re-use assets and I have a terrible sense of direction which ends up in wandering around the same area 20 times in frustration.

Don't care too much about graphics - its the interface that gets me.

I have a hard time playing first person shooters which don't support a WASD style control scheme (Wolf 3d, Blake Stone)

I can no longer stand to play games like Expendable which have a fixed overhead / isometric viewpoint and "tank" style controls.

And I will not touch an old RPG which requires me to make my own maps (Ishar, early Might & Magics, etc)

This.

I am more lost in real life than Marcus Brody in his own museum, and the fscking games want me to draw my own maps? Get out of here! :-)
