Killzone. It is very much a flawed game but there were so many little things in this game that just put a smile on my face. Like the picture above for example: the graphics are outdated and textures blurry but I can't help but adore the aesthetic!

Heil Helghan!

Dota 2. I can see the appeal in it, and id like to get good at it but it has such a big learning curve that i just dont feel like putting the time into it

EDIT:  Read the title wrong

zelda skyward sword.

Rampage (arcade, master system). Very repetitive and not very balanced, but so absurdly fun.

Jericho (PS3). Low framerate, bad gameplay (character shift, power/character balance, even buttons are wrong), upscaled resolution, the graphics are not really good, the quicktime event are awful, even the story is not really great, but the horror part of the game is really splendid, . It's not just violent and gore like God of War, it's not like a movie because you are in charge, it really has a good horror atmosphere, more specifically, a Clive Barkley atmosphere. I still remember a few scenes, like the marble covered in shit and blood, the kid ghosts or the crucified guys you can kill or not. The game really impressed me, that's one of my best games, but it's not a good game, the PS3 port not good, it has 60% metacritic and sold like shit.

Its funny you mention Rampage, I was just gonna come back and add the N64 port of Rampage to my list xD

Wasn't really a great game for the same reasons you gave, but I loved playing it when I had friends over.

Ninety nine nights

*edit*  Nvm.  Seems this thread is about average games that you love more than bad games you love.  So I guess I'll say Stranglehold.

fable,
there are actually nothing special, but i can´t help but love them

Deadpool. I've heard the game was funny but lackluster. But I still enjoyed it a lot.

Umm... a couple of others are Marvel Nemesis: Rise of the Imperfects and X-Men Destiny.

Also, Driver: Parallel Lines. It's a guilty pleasure of mine.

I thought we this thread was about bad games?
