Nearly 5 stars
This is an excellent implementation of a Wipeout-style game, especially as an initial release.
On an iPad Air 2 the graphics are detailed and smooth; the accelerometer controls take little time to get accustomed to and work well.
While theres nothing really wrong with this game (and plenty of things right), it has enough room for improvement to reserve the final star for some of that.
Multiplayer is an obvious potential addition, though that may not be technically feasible for this game.
Another improvement could be cinematic or slow-motion camera work during key events such as takedowns, akin to what we see in the Burnout racing series for example.
Takedowns themselves could be made more dramatic, and a greater variety of powers to equip your vehicle with could add some additional excitement.
I certainly appreciate the ad-free and no in-app purchase model. I dont mind in-app purchases if they are done tastefully and truly provide value that isnt necessary to enjoy the core game.
Bottom line is that if you enjoy the futuristic Wipeout style games you will enjoy AG; it is the best implementation of this genre currently in the App Store. Just dont expect the adrenaline rush of Burnout.
