G0-T0 os THE most useless character in the game, his slot could have been better used for another non-droid NPC character. Maybe one of the other characters from K1 could of come back, no, i don't mean revan, then we wouldn't have the possibility of a K3. Maybe carth, who is in the darkside path, could join you, and i dunno, that would change the story, he would probably take you looking for revan, and maybe kreia could be bastilla (also quickly mentioned) what do pple think of that.
