Well, if I could remove a game from existence. No questions asked and no wrong done. I'd kill WoW.
This game is the most harmful thing to have happened in the gaming genre. It butchered the lore of Warcraft and turned millions of people into mindless husks. WoW isn't a game. It's a place you meet up and grind indefinetly. I think people can do better than this, regardless if they like it or not. Might as well just remove the game from existance. Also, dumb corporate people always try force game-makers to make their MMO like WoW instead of creating something original. Too much money is wasted into projects that can't compete with WoW, and because of it, those studios get closed down shortly after. Why can't game companies just focus on making good managable games? Start out small and then build up the player base? Actually, maybe that's what newer companies get for being stupid in the first place.
Ah well. Guess it's a good thing WoW exists. Survival for the fittest and all that.
It's not like my friends play that dumb game to begin with so what do I really care anyway?
So I guess I wouldn't remove any game.
