Ace Combat: Joint Assault Review at CheatCC
CheatCC says, "It’s kind of silly the developers decided to use the whole real world setting in a way that doesn’t take advantage of either the PSP’s hardware or the narrative, it seems like they could have spent more time creating a game that echoed their last portable installment less if they hadn’t, but for what it is, it’s still not bad (it is still Ace Combat after all). Joint Assault might not be the strongest entry in the series (though you can’t realistically expect a portable installment to necessarily measure up to a more advanced console version), but true solo-flying aces may want to consider a rental before committing to this sortie."
