just got this for my PSP and yes it is in japanese but it will lay on us psp's as well and I have to say it is a great game. The closest thing to is is Gundam vs Zeta Gundam but controls better, better game play and a lot faster. there is another macross frontier game out there but I chose Ultimate over Ace for one simple fact. Ultimate has more Mecha to pilot. in ace you have the main Veritech of the shows (macross,Macross DYRL , Macross Zero, macross 7, Macross Dynamite 7, and Frontier) while in ultimate you have jet fighters and all the veritechs from all the macross shows and the destroids, the enemy crafts and if you want to Pilot the SDF-1 or Macross Quarter you can.
the controls take a while to get used to so I suject to practice in the tutorials first
