Are you so silly that you only play one MMO at a time?

I am. Mark Jacobs said in a recent interview: "I play multiple MMOs... the idea that you only play one is really kind of silly." And he talks about research having been done on that subject: "We've done surveys on that, the industry has done surveys… so any comment along the lines of 'well if they're in my game they're not playing in another game,' flies in the face of all research that's been done among MMO players." Hmmm, I wasn't aware of that research. Anyone got a link?

Personally I have terrible problems playing more than one MMORPG at the same time. I am monogameous. The fundamental problem is that these games are designed to suck the maximum amount of time out of you. Playing one game for two hours is a lot more effective than playing two games for one hour each. Of course there are transition periods, where you decrease your activity in one game, and start up the next, and still are subscribed to both. And technically I'm "playing" Guild Wars and Lord of the Rings Online in parallel to World of Warcraft and Warhammer Online right now, plus a number of free games. But only if you consider having a valid subscription as being the same as playing a game, which kind of breaks down as concept with games that don't really have a subscription or where you bought a lifetime subscription. A better definition of "playing" is actually logging into a game and doing more than just emptying your mailbox. Practically for me it is hard to imagine playing several MMOs on the same evening.

So lets add to this research and do another survey: Do you frequently play more than one MMORPG on the same day? How many monthly subscriptions are you usually paying for in the same month?
