Well, I'm torn. Half the commenters are naming games that are of a reasonable quality but they seemed not to like it personally for whatever reason (primarily for cash-in, it seems) and the other half are naming games that were probably covered on Angry Video Game Nerd due to their unequivocal awfulness.
So I won't stir a hornet's nest by saying something like WoW because I refuse to do subscription-based gaming or Halo just because I don't play it, because there's nothing really wrong with the games. And I won't waste my time looking to see if Master of Orion 3 or Quest64 has been mentioned yet, and just say, look at the AVGN video catalog. If your game is on there (except his positive review of Mario 3), you should never have made it.
