WoW really comes down to a "do quest, get item" MMO, which works for it, since Blizzard can do anything and wind up succeeding. It's good stuff, and is quick in leveling compared to other MMOs, but it's just terribly boring once you finish all of the 60-only quests. I haven't gotten TBC, and I don't plan on it.

Also, it costs money. I can't afford that.

To be completely sure of what's going on, simply change the above statement from "horribly wrong" to "insanely correct."
