This game went WAY into the strategy direction. It resembles advance wars more than anything else. The side-scrolling segments are gone and we left with just turn-based combat. Another big change is the player no longer controls the monster but the human military.
There is nothing wrong with this game, but in today’s world if you are hungry for a turn based strategy game like this there are many more good ones to emulate. Check out Fire Emblem, Advance Wars or even Final Fantasy Tactics.
