I don't know, by why would you even think about buying it from XBox's On Demand service? They overcharge for every game on there. They actually have the nerve to sell that goofy 50 Cent Blood on Sand game for $59.99! A game from 2009 that retails for about $15-$20 at GameStop, and can probably still be obtained at even cheaper prices elsewhere. It's a scam.
I don't think the convenience of not having to put a disc in is enough to warrant purchasing anything On Demand. --- The People's Heel IF YA SMEELLLALALAO..WHAT THE ROB IS COOKING !!! 'B-|
