Wow was fun, but I'm not sure I'm going to be able to put that kind of time into a MMOG again.
Plus I'm really looking forward to getting my monies worth out of HL2 and Bloodlines. That will take probably a month or so right there. Then some HL2 mods will hit.. then some other new games will hit, probably. Then I will have to buy Christmas presents... sooo, I dunno. GuildWars was great fun.
