I'm console loyal in that I've owned everything Nintendo has ever put out, BUT I will play on any and all platforms and I own a variety. (I've never bought an xbox, though...)
When it comes down to a really good game experience, especially with MMOs, I defer to my gaming PC. I find my PSes and Wiis are good for more chill, group/party-oriented games, whereas the PC is good for deep strategy and online experiences.
I like EVERYTHING!
