Wjy dont you try it by yourself an post your experience? With titanium backup it should be no problem to buy it, to back it up, test it in timeframe of 15 minutes, and if that isnt enough, decline the transaction an restore from backup. If you are lucky, the game works beyond. Some games have checks, so you could try lucky patcher. Dont use a cracked app from anywhere, it will not be shown in freedom, because of the missing market link.
because i ask first in case anyone tried it already,
you can tb gamevil games, yet you can't restore the purchase, at the same time it works with freedom, other games are serversided (heros of order and chaos) yet it also works with freedom. if you cant answer to the questions don't answer.
