Showing my age; I used to love Paperboy. Globalcore has a way that you can play the game and get some exercise as shown in this video.

The game is built in Unity with 3D assets created in 3D studio and textured in Photoshop. The KickR sensor detects the speed of the bike and has the ability to provide programmatically controlled resistance. The KickR communicates speed and cadence through Bluetooth to a nearby iPad which updates our app over OSC.
