Super Smash Bros. The games themselves I love more than anything, but the community itself I find obnoxious and elitist. The few times I went to tournaments I met a few cool people, but most were just socially inept dudes with a dickish superiority complex because they're good at the game.

Also, I like to watch matches of the best of the best duking it out because it's just ridiculous to see how these guys have mastered every aspect of the game, but much of the time the dudes commentating it make it almost unbearable to watch. Here is a great example of two of the world's greatest players in an excellent match, but the commentating just makes want to stick a pencil in my eye. Of course you've got the odd situation in which the commentators are good (Wombo Combo et al), but it's a rarity.
