The only one I've played is Air Force Delta Strike for PS2. I'd say it's like a poor man's Ace Combat, basically, with a lot of interaction between the characters between (and during; there's a lot of radio chatter) missions. Graphics and gameplay are decent, you can unlock a nice selection of aircraft, and you can easily find it on the cheap now if you look around. If you've already finished AC5, it's worth a look.
