E3: Games-on-demand does re-downloads
Prices "comparable" to retail.
Microsoft's upcoming games-on-demand service for Xbox Live will be updated every week, and it won't be a problem to re-download things.
Announced on Monday after the Microsoft conference, the service is starting up this August, and the platform holder said yesterday that prices would be "comparable" to retail - with USD 19.99 for LEGO Star Wars: The Complete Saga offered as an example.
Games can also be re-downloaded if you have to delete them to make space at some point in the future, and this will also mean that if by some miracle you need to buy a new Xbox 360 or get yours replaced, it won't be a problem to download them again either.
Other than LEGO Star Wars, games confirmed for the service so far are BioShock, Assassin's Creed, Mass Effect, Sonic the Hedgehog, Oblivion, Crackdown, Colin McRae DiRT and Call of Duty 2.
