I'll probably use more music on some of the other missions. Some of it will be from the Ace Combat series, other bits I might steal from elsewhere. I like using music to give a sense of atmosphere to what's going on. 
AC: Infinity is [i]okay[/i], the campaign is disappointingly short at the moment - though they may be releasing more missions - and the multiplayer is good, if a bit repetitive. I drift in and out of it quite a lot. I've been replaying the older games though, and I still love them to bits.
