A more involving Story and this would be Game of The Year.
This game is very polished, the upgrade system works very well to keep things fresh, it is even possible to break the rock-paper-scissors mechanic if you are clever and are co-ordinated.
special attacks from units and off map support feel very powerfull and and extremly gratifying to use, however dont feel overpowered and unfair when used against you. Some people claim its all to simple, but deep stratagy can be employed, a few games i got my ass handed to me by people who knew a few sneaky tricks.
In all its a fresh break with conventional RTS and also an amazing feat for it to be done on a console.
If this could have all been achived whilst maintaining what should have been a promising and inovative story line this would be an even more fantastic game. Dont expect much from the campaign in terms of story, but expect both the on and offline elements to be addictive, fun and competitive.
