Wow, don't you feel accomplished now, jhucks? You have very strong virtual characters. Maybe you should go back to first grade, though, to learn how to count. You skipped from three to five when listing your reasons for WoW being good.
I would consider at least half of the players in WoW addicted. As in, they will play every day unless physically incapacitated and blow off some responsibilities just so they can grind some more.
WoW is old. In its time, it was a great game, back when Blizzard was still young. Now? Blizzard can make as many expansions as they want, but the golden age of WoW has been over and will never start again. It's way overrated.
