Although purely an online game (can’t be perfect), Spectromancer is the latest brainchild of Richard Garfield, he who brought you Cosmic Encounter [Update: I knew that, duh!] Star Wars TCG and Magic: the Gathering. Other contributors include Alexey Stankevich and Skaff Elias. The system is based on Alexey’s popular Astral Tournament.

It’s a classical card game, and sounds like it combines elements of both ccg’s and rpg’s into an online format.
