FFVII - Cloud sucks....but that's why I have the PC version and cheat, I turn the "hero" into Sephiroth and make Cloud the villain and kick Cloud's sissy ass, any time I decide to replay the game now.
EverQuest - An entire decade of my life and my first MMO... but I got burned out after being a raid leader for half of those ten years. Heck I'd have to buy the dang game again, I can't even find my CDs or account info anymore for either of my accounts.
WoW - Became a dragging, play because you have friends playing game. Still don't know if I'll play again or not. Leveling has become a daunting chore over the past couple years as the game has changed. Getting to level 60 was easy, even playing as a healer. I may have basically soloed to about level 16-18 but from there on I was always in a group running through some instance. But then they changed the game, and ever since the Burning Crusade players have had to spend more time doing stupid go and do this or that quests till their eyes bleed to get levels. And as a healer type, it royally sucked...I managed to get to level 77, but by then I had enough. Because then it became an issue, oh well if you don't have gold for this or that then you can't do this. And what was I suppose to do, try to start a 'cyber-whore' ring on WoW to get gold?
The Operation Flashpoint Series - someone said they didn't like the realism of the game? They evidently picked up the wrong game to begin with...that was the entire point of the game, to be as realistic as possible. Without actually having real people shooting real guns at you and you having a gun and shooting back at them; all while sneaking or running around.
Games I Definitely Won't Play Again:
Final Fantasy XI Online - while it started out ok, it just became daunting when you finally figured out what you had to do to get access to any of the fun classes.
Diablo 2 - the point of the game was to what? see who had the best "hacks" right? I hope Blizzard does something about the rampant hacker issue when Diablo 3 comes out.
Star Wars : Empires At War - Forces of Corruption - without FoC, the game is fine...but whoever came up with the dumb idea of the pirate faction and their corruption ability needs to be shot. Pirate faction, alright fine....but honestly do we really need to have planets being "corrupted". Especially since only like 1 or 2 heroes per side could remove corruption and you had an entire galaxy you were trying to control. It got super annoying, super fast. That and they moved Darth Vader to the "commander" of the SSD Executor which means you loose his TIE Squadron which early on is doubly annoying since he's one the Empire's strongest ground units as well.
