At some point, possibly in the next month or so, I'm going to buy a 360. I'm not necessarily going to buy many games off the Marketplace, but I have a question in regards to XBLA game purchases. I know with the Wii Virtual Console games, you can redownload the games, at no additional cost, if you delete them from your system. Is that also the case with XBLA games? If I buy a game off the Marketplace and delete it from the hard drive, will I be able to redownload the game for free, or will I have to buy the game again?
