I appreciate good graphics, but it's all relative. I don't consider games on older systems as having "worse" graphics. I consider the capabilities of the hardware, and I care about good design.

But I'll give anything a shot, and if it's fun, I'll keep playing even if it's ugly.

Oh, and one thing that is really important to me is the use of color. It's not like I want my games to be candy-coated, but there have been some modern games where the entire palette for the whole game looks gray/blue/brown. I find that really depressing and a huge turn off.
