Best 3DS game so far, just as good as Ace Combat X and X2 on the PSP. Visuals, music, gameplay, all outstanding. A really neat modern updating of Ace Combat 2, with some features added from the Wii game Sky Crawlers. The story is presented in a really abbreviated and sketchy manner, you'll have to read the Ace Combat 2 Wiki to catch up, but when you understand what's going on, it's good.
I'm waiting for Bandai to release the WonderSwan/SwanCrystal II and blow both the Vita and the 3DS away.
Paid it for full, and enjoyed the hell out of it. I haven't really unlocked everything, there's still so much left I have to do in that game, but it's a very fun flight combat simulator. Plus some of the levels look gorgeous (like Tin Can, where you fly around during sunset!).
pardon if my posts suck, i post by tapping on the handset button on a one-way analog handset. i saw Hannibal Lecter do it.
