Gentlemen, I highly encourage you to join this. The Throne Room provides the best RP experience around, and if you're looking for a really immersive, long-running game, this is your answer. Naturally, you can go shorter as well, but for maximum effect I'd take a character. These things have been known to last 15 months in the past and are truly epic experiences.

Don't have M2TW? Go out and buy it. It's worth it to join one of these.
