I picked it up at gamestop during the last 25% off PSP coupon. It's really fricking fun if you're looking for something old school, arcadey. If you go in expecting incredibly deep gameplay, you will be dissapointed. If you want to fly actual jets really fast, blow stuff up, dodge some obstacles, fly really fast, with a bonus of upgrading your collection of replica (in appearance) jets, you'll probably like this game. The only negatives in the little bit of pop-in (which is pretty far back, noticeable without affected the gameply though) and the difficulty to consistantly avoid enemy missles.
