I try not to have a standardized bunch of criteria when judging games, old or new. When I judge a game, it mostly boils down to "did I have fun with this game?"
If the graphics or game mechanics are (to me, anyway) so bad that the game is unplayable, then the game isn't fun, and clearly wasn't the right choice for me.
Sometimes though I'm willing to power through graphics/mechanics that bother me if it's a game that the gaming community as a whole seems to think very highly of. For example, Planescape: Torment. I missed this game somehow when it came out. When it went on sale a few months back on GoG, a friend suggested that I try it out. The graphics are fine (very similar to Fallout/Fallout 2, which I adore), but I found early on that I really couldn't get into a lot of the gameplay mechanics. It really didn't feel like it was the right game for me, but because of its amazingly good reputation, I continued onward. I'm glad I did, because the game was awesome and had some of the best writing I've personally experienced in a game.
