I adore starcraft, but I feel anything that makes be a single player within the UNIVERSE is just not going to be fun anymore. WOOT! IMMA PAYING 15 BUCKS A MONTH TO BE A COG IN THE MACHINE!!
Sure I can see myself playing a cool zealot, but again, the suspension of disbelief is just too ridiculously big. A multiplayer game where you play a single character in a battle fine (ie ghost). But not on an RPG scale.
