Champions Online
For all you City of Heroes fans out there. Cryptic is putting out a new superhero MMORPG based on Champions. Apparently it will be rather cool. I'm grooving on the cross platform since PC and 360 will be able to play together. I've already started on my hero, but can't wait for the inevitable villain expansion. The combat system won't be your typical MMORPG type. It will be more fluid and instant closer to fighting games but still keeping the loot and resource management of the MMO's. Anyway check it out if you haven't already.
