I've enjoyed a few that have been panned. Master of Orion 3 on the PC got ok marks from some mags, got blasted in others, lot of MOO fans thought it was crap, but I like it. I still have a game going that I started shortly after it came out. I think I'm on turn 510 or so.
Time Killers in the arcade was a great game to me and most of my friends, yet it got destroyed in reviews. That horrible Genesis port didn't help any, either.
Then there was another fighting game on Sega Saturn that I think was called Battle Monsters. The kindest reviews give it a 7 out of 10, average review gives it a 2 or 3. It's one of those games that succeeds in being so bad, it's actually good.
