I'll have to keep a look out for it. It did sound like fun, but my local gamestores have been keeping their shelves pretty bare as far as releases for any of the systems. It's driving me up a wall.
Yeah, it is for the PS2. I am unsure of the story, but includes customizable mobile suits. I did play it for a few minutes at my local eb. I skipped the story to play longer. The first battle was a GM vs a Zaku 1. An easy battle, which you could take stuff from one to the other.
I'm about an hour into it, and so far the game is pretty cool. While I'm disappointed that the suits are chibi (although I knew they would be) it's still pretty fun. I just can't wait to actually get some good parts to customize with (I need some satellite cannons or VSBRs...hey, a man can dream).
