Do you play similarly themed MMOs simultaneously?

So RIFT and EverQuest II are both expanding this week, and I've got something of a conundrum when it comes to spending my game time.

On the one hand, EQII has more features than any other themepark in existence, and I've got a long, fun history with the game. On the other hand, RIFT is newer, shinier, and boasts a nifty riff on player housing that I'd like to experience.

Part of my brain balks at the prospect of playing two fantasy MMOs, though, and with so many interesting games out there, I can't help but feel like I'd be missing something. What about you, Massively readers? Do you play similarly themed MMOs simultaneously?
