Only played the PSP one, got bored (though I didn't get bored of it as quickly as the people around me did), stopped halfway. 30+ fighters easily catches my interest. XD
I kinda liked the Japanese AC6 trailer though... but when you watch it again and again you learn to realise that it's more or less fluff to sell something below expectations... (I'm
not implying crap, just "not what I expected", that's all).
Now if only AC had those fightercraft from a certain anime... I might jump all over it, I might not, but oh well. Fictional aircraft duking it out with real-world stuff looks fun for a while, they might as well expand on it XD
