I'm sure this is how TB fans will spin it, but I wouldn't buy that spin at all. If a TB mode can work well in a RTwP game, the same is equally true the other way around. Claims to the contrary are merely self-serving, imo.
You are wrong. Anyone who actually played the Original Sin games would know that the combat would not be balanced by flipping the switch to "real time". It's false to say all games will work equally well in either mode. That's like saying that a circuit designed with diodes will work the same way if you just reverse or remove the diodes out and reverse the current.
Anyone play, say, Diablo III? How would that play if all you did was make it turn-based instead of real time?
