Bad games in your opinion.

I'm with you on that

Minority Report, that game is so ugly it is glorious.

Recently i would say Asuras Wrath..i enjoyed the hell out of that game!

Lord of the Rings: The Third Age. Horrible plot and simple gameplay but it has it's own charm and it's fun to have your own little Middle Earth adventure.

Me too!  You're welcome at my home any time!

Mindjack. I went in expecting a horrible game, but in the end I had a lot of fun and enjoyed it more than many AAA titles with 30-40 points higher metascore.

Knack. It was pretty fun at first then I wanted it to end about chapter 11. The last chapter was fun once more, enough to make it the best bad game i played.

Earth Defense Force series. Looks terrible, has a terrible frame rate, and the story is just dumb.
But, it's just fun to play through with a buddy. My primary gauge for rating a game is asking, am I having fun? If yes, I don't care what it looks like.

Games like Wii Sports Resort or Mario and Sonic at the Olympic Games. They are clearly lacking in some of the quality departments, but when you get a party together they are extremely fun.

I can also say Skyward Sword because people are still sour about it.
