Three months after debuting on Android Market, Grand Prix Story, the latest sim from Game Dev Story creator Kairosoft, is now available for iDevices, allowing you to manage an auto racing team for just $2.99 (special 25 percent off release sale price).

In Grand Prix Story, you'll "become the boss of your own team, training drivers and acquiring sponsors before conquering the Grand Prix". Along the way, you can develop new vehicles and parts, customizing them to perfect your racecars. 

Also out today: Amanita Design's Machinarium, the acclaimed adventure title and winner of the Independent Game Festival's Excellence In Visual Design award. If you've never played it and if you have an iPad 2 (no support for original iPad), this is definitely worth your $4.99!
