A fun game that's quite enjoyable.
I haven't had any of the problems the reviews have said they've had. There's a tiny bit of lag at the beginning of one or two stages but that lag only lasts for a second or two then it's gone. The gameplay is smooth and it's easy to figure out. The mobile suits look great and they're very realistic. There isn't much story to the game, but it assumes you know the story of the Universal Century and the One Year War. If you don't know the story of those then the game will probably confuse the heck out of you. The game is fun, there's no doubt about it, and it's worth checking out for any Gundam fan. Don't expect amazing things from this game, but it's definately a fun game and a worthy addition to the PS3. This game is highly under-rated, which is very sad. But perhaps what's even more sad is all the people who dislike this game feel that anyone who does enjoy this game are morons. I don't know how many times I've seen people say "if you like this game then you should die". They simple can not understand that not everyone sees things as they do and they believe that they're so right and everyone should agree with them.
Check this game out for yourself and make your own opinion. Don't go by the idiots who make comments like that. The game is fun and I enjoy it. Simple as that.
