Seriously. I f you were expecting Bioshock or Halo, you bought the wrong game, And someone should take your 360 away!
Is it bad? no. Is it great? Mebbe if you're a dynasty warriors freak perhaps. otherwise it's pretty average. The level design is creative for a DW game, and the zone control is a nice departure from the requirement to kill generals to take over areas.
That said this is next gen and no gundam game seems capable to grasp this. I had levels this detailed on my Dreamcast. Koei stop embarrassing yourselves, and insulting me. Do it with some flair, or stop hogging the shelves at the game store. Also the gameplay is very very repetitive. But if you've played a DW game you already knew this and are fine with that. The explosions are cool, the controls are pretty solid, though many of the gundam mechs could have been left out. They did a poor job with many of the lesser models special moves. "Wow strafing and shooting! I've never seen that in a combat game!" I mean please.
And Namco Bandai shouldn't even be contributing here. They should be focused on making the next ace combat game, or starting up the xenosaga series again. But I assume they have the rights to gundam so...no accounting for taste I guess.
All in all...DW gundam is fun for 1/2 hr, mebbe an hour or two. After that? Not so much. Rent this puppy.
