Bad games that are surprisingly fun

Guncraft, a lot of guys says that game's suck but I think is strangely fun ^^

Eversion. It's VERY short and the controls emulate being on ice 100% of the time, but it's sort of fun. It's like a worse Super Mario.

I have enjoyed Resident Evil Operation Raccoon City. Same with Land of the Dead Road to Fiddler's Green. ( Keep in mind I played that one with fan made patches. )

I also enjoyed the Resident Evil Outbreak file 1 and file 2 games, and Postal 2, and the expansion for it. Dead Island and Dead Island Riptide I guess could be added to the list as well since due to launch issues there is a lot of hate for the first Dead Island game.. Funny enough I did not have the issues others had with that game..
Deadly Premonition can be added to the list.. funny enough I am soo looking forward to the HD remake on the PC.

I could probably think of a few others that a lot of others seem to hate but I have enjoyed.. but I just do not feel like sitting here and going through all the games I have played :P

I can't think of any blatantly bad games at the moment, but I loved Assassin's Creed III, not only did I enjoy the story and the characters but I never found any glitches. Apparently most people don't agree with me though.

Either way, I'm super hyped for AC IV and Watch Dogs, and I will post a better answer here once I think of one xD
