There will be a few Gripe-ers for any list. But for the most part, any of us who would play the DC should all fall into a similar niche demographic and be looking for the same types of game.
-make the list. 20-25 games
I disagree entirely. Just because we are here does not mean that we would truly have similar taste in console games.
Take Goz's example. I have and enjoy Tokyo Bus Guide on the DC, but you should see the looks on my friends' faces when they see the game.
Just go to gamespot and look up games by score... it's a quick simple way to get a good idea of "good" games. Otherwise, these threads would get messy quick IMHO, with people saying this game is crap, and that game is a treasure that no one knows about, etc etc.
