Damn it now I gotta decide between Breaker, Unicorn and Full Boost.
I've played a bunch of that PSP Gundam vs Gundam game despite not liking it too much. It's just kind of confusing but pretty for a PSP game. I think that's kind of soured me on Ex VS because it looks like something you're really going to have to dedicate yourself to to have any fun with it.
Not sure about my feelings on Breaker. Gameplay doesn't look too great and it appears very japanese-heavy on a first look. I do like the idea of building your own Gundam but in the end I'm still going to want to pilot just regular-ass Zeta, Nu, Unicorn, Sinanju or Exia.
Sucks that Unicorn doesn't have any multiplayer, not even local it seems like.
But the stuff looks hot and you get a Delta download code I think. Single player campaign seems fun and pretty understandable with minimal japanese and having seen the movies.
At least I find Musou games awful and boring so that one's out of the picture.
