I own Mobile Suit Gundam: Crossfire, and don't plan on getting rid of it, due to my Gundam game obsession. The controls and the frame rate are horrid. Actually, that's too kind of me. It's probably one of the worst videogames I have ever played, and I've played some bad games. The frame rate is atrocious, and the controls are beyond broken. The music is awesome, though.
I remember when everyone at GAF was fawning over that early footage a couple years ago... obviously none of them had ever played a Gundam game before. I tried to warn them, but they wouldn't listen.
I'd love to see Operation Troy, but I'm guessing it's dead and buried by now. I know it was shown at TGS, but Bandai still has it listed for a release in 2007, and they've awfully quiet about it since.
