Awesome, thanks!
Man, it's too bad the Super Gundam isn't included in this game, especially since that's what Emma uses in the final battle in this particular mission.
Yeah, I would've loved to have the Super Gundam at my disposal in the game.
BTW, I think I agree with you regarding the reasons why the Psycho Gundam isn't in this game. For whatever reason, the Musou engine must not be able to handle such large enemies. When I fought the Elmeth (another very large enemy), it just stayed in the background and I had to fight off its bits...but I was never able to fight the Elmeth itelf. So the game engine probably isn't designed for such large foes.
I think it's an issue of scale more than anything. If you look at other Musou titles, all the characters are relatively the same size.
I'm sure they can figure out a way to handle this in the sequel. Maybe add a double jump to the Zeta or other flying units so they can reach the Psycho's head when they hit it. The Psycho just has to be a boss character, doesn't have to be playable!

My wish list of mecha for a Musou sequel:
Turn X
Kapool
Acguy
Zock
Zaku I
Gyan
Zudah (prototype suit from MS Igloo)
Psycho
Psycho Mk. II
Quin Mantha
Kampfer
Gundam Alex
GP01
GP02
GP03S
Super Gundam
GM Custom
Guntank
Groundtype Gundam (give us a GM Head while you're at it)
Groundtype GM
Gouf Custom
GM Quel
Doben Wolf
Zaku III
Nu Gundam
Sazabi
Re-GZ
Jagd Doga
Geara Doga
Jegan
Heavy Gundam
Full Armor Gundam
Perfect Gundam
Gundam X
Gundam X Divider
Shining Gundam
Rising Gundam (since it's basically a Shining re-color with bow and arrow and spear)
Nobel Gundam
Maybe some mobile suits from Gundam Seed to make MAF happy.
And while we're at it, I wish they'd give us some custom colors...Amuro's Zeta Gundam, the realtype colors for the original Gundam, etc. Not all of them have to be playable (though I'd love to play fencing-style with a Gyan), but to be able to fight against them would rock.
