The game has such a strategy depth in openings, matchup-specific options and etc that any major change in the game dynamics would be seriously questionable. IMO, it would be like changing chess rules.
Though, it is not an option not to evolve the technology (graphics and sound) and game engine but would this be enought content to develop a sequence.
I'd like to know the gamers opinion on this... CAN there be a SC 2?
