dood says he wants an unpresidented amount of content in SC3, wants players to be FULLY satisfied with this one game.
They're putting in a FULL create character mode !!! yes! that was 1 of the 2 big things i was waiting for, being able to make up your own characters is going to be sweet.
the other big thing im still waiting and crossing my fingers on, Online play. they had said after SC2 that they wanted thier next one to have online play.
