Ubisoft tipped us off to a new Flash game they've made to promote Prince of Persia: The Forgotten Sands. Now, it may just be that I've been playing a lot of Tomena Sanner lately but I think this is damn good.
You can check out the game here. I do recommend it. A surprisingly fun diversion, this.

I suggest getting MIRC (if you have a PC) or X-Chat Aqua (if you have a Mac). Channels you would want to join to start off would include #fluodome, #moo, and #warau. You can also join #smogon or #stark if you like, but those are larger and odds are you won't feel comfortable in conversation there until you have lurked a while.
The Priority system is based on how many games you are currently playing in. If you are not currently playing in any games, you may sign up as P1. Of course, you may also not sign up as P1 if you don't want to, but there isn't any reason not to if you actually want to get in.
