I got this game right after it came out, and I just got a chance to play it (I would have done it sooner, but my PS2 was getting repaired). So far, it is really good.
In addition to cool CG scenes, the game has plenty of footage from the series, as well as voices and such that come up during the missions.
My only complaint with the game is that the controls are somewhat counterintuitive, although they were necessary to get the full 3D movement in space. Still, it would have been nice if they included a button to rotate the Gundam.
The part the seems most interesting it the ability to play as gundams from other series, increase their stats, and then use them to fight in versus mode. However, I haven't tried this yet.
Has anybody else played this game? What did you think of it?
