"All of the compromises and omissions that were made (or not made, as the case may be) to bring Ace Combat Advance to the GBA have sucked out everything that made the franchise so appealing and so interesting on the console. Fans expecting an authentic Ace Combat on the go are sure to be disappointed. That said, if you're merely looking for a portable shoot-'em-up, Ace Combat Advance does have enough going for it to offer a few solid hours of aerial combat."
