Asphalt 5 price drop
Retina graphics, cool cars
Drive aspirational cars around aspirational tracks in this well produced and accessible driving game. There’s an impressive Bluetooth multi-player version that lets up to 6 people play, in addition to online multiplayer.

Usually on the pricey side, this is currently available for 69p (99c) from iTunes here. And if even that’s too expensive for you there’s an Asphalt 5 free to try.
