1. Counterstrike
Usually, if I don't like a game I just don't play it and everything is good, but with CS that changed. At any LAN party, everyone just wants to play CS. Heck, this game isn't fun, it's just stress for me! Always having to worry about finding the enemy while staying alive just to avoid being cursed at by friends sucks. It gets worse if you take the physics into account. I mean things like not being able to move while being shot at, going down in so few shots, etc. It's just so infuriating I want to throw things at people (or crash the server) just to get that anger off my chest. I'll keep Serious Sam in reach if it gets that extreme this time again.
2. Zelda:WW
Well, not really evil, but nothing I went "whoa!" about. Thinking back I can't really remember a game that made me go "whoa!" except for the Tales of Symphonia trailer, though. Nonetheless, while playing the game was that "Just one more dungeon" experience, playing it again after putting it away cost me a lot of willpower.
3. Super Mario Sunshine
The game got boring once all of the events in the main town happened. At that point it stops to be really interesting and there's not much more happening.
4. Super Mario World 2: Yoshi's Island
I'm not that sure what put me off, but I definitely didn't like it. The game was too damn short and easy.
5. The RTS/FPS flood on the PC
Okay, it wasn't that bad, it made me get that little black block that sits on the ground in front of my TV...
6. GTA Series
Well, uh... I don't like it. Sure, it's fun for 5 minutes while you do all the things that you couldn't do in real life/other games, but once you're through with that it's mostly over. Sure there are those missions, but I didn't find them interesting. The worst thing is this game really shows how much people love brainless violence. People ranting about how the GC needs more violent games, etc. I support enforced age minimums just for the sole reason to keep all those jerk-off-to-blood children away from this game (at sight distance, so they suffer from not getting it!). I also hate people who love Rap/Hip Hop for the violent or drug centered texts. I just can't help, I always think lack of education is responsible for that mentality.
Note: These are ordered like they came to mind, not by annoyingness.
