I guess his response shouldn't have surprised me, even given his enthusiastic praise of Age of Conan. It seems like World of Warcraft operates as many gamers' home base. They might leave for a while to try out a new MMOG when they inevitably burn out on WoW; but most eventually gravitate back. The return might be in anticipation of an expansion, it might be that the gamer misses his guildies, or maybe it's the old, comfortable game mechanics. Whatever the reason, many of us can't seem to escape the black hole that is WoW; and maybe that's partly because we don't want to escape.
I know that there are definite exceptions to this trend; those gamers who cancel their WoW accounts and never look back. But for many of the gamers I know personally, something always pulls them back to WoW and hooks them again, usually for several months at a time. Even when they're playing another MMOG they often keep their WoW accounts active to check in on friends, run a random instance, or do a little PvP. Which makes me wonder, are multiple MMOG subscriptions becoming more common?
