A portion of the PVG review:
"Yes, the core mechanics remain the same, but the gameplay has been tweaked to not only make the game more strategic (and less reliant on luck), but to balance just about everything in the game. For example, CO powers are no longer the drastically powerful, game-changing forces they were previously. Instead, your CO is actually embedded into a unit on the battlefield, with that particular unit emitting a range of effect that gives bonus stats to all units within that area."
