Guilty Pleasure Game?

I have a question for everyone what is your favorite game to play that is, by way of ratings and critical response, a "horrible game?" This could be a game you never tell others about because you are ashamed to let people know you play or something in the strain of that! Or we can even expand it what is a video game character or game that  you have fallen in love with and you know you would get flack from your friends for admitting it? 
 
As for myself I very much enjoy the Samurai Warriors games, there is some kind of simple fun there that just keeps me hooked!

FFX-2, however i'm proud of it, yuna rules and you actually get to choose which missions you want to take on which is like mass effect.

Every eroge in existance.

I don't play it anymore but I used to play Minority Report on the GameCube.

Inb4 rapelay.
 
And this one game called Saya no Uta (Saya's Song). I don't care if my friends make fun of me for playing it. I love Lovecraftian horror and this game, with its chilling music, visuals, and psychological edginess are right up my alley.

Project Snowblind, I was hooked on that game's multiplayer for a long time.

I still play worms armageddon with my little brother  :)

You start sharing, people then begin to judge you, the name calling begins...no good can come of this.   
 
I'll just say there are some things on Hongfire that I am ashamed to say I've tried...and upgraded...and then learned how to mod.  I'm not a proud man. ;-p

Warhammer Online for me. The very definition of a middling MMO, objectionably. But I am loving an hour here-or-there for free.
