Loot Ninja writes: "Microsoft's new Games on Demand service has been both praised and scorned by various members of the media. Regardless of how you look at the service, it's worth investigating. We recently got a copy of BioShock for Games on Demand to test and were fairly happy with the whole experience. This won't be a review of the game, as we've already done that twice (Xbox 360 and PS3), and as everyone knows it's amazing. This review will instead focus on the Games on Demand service, how it compares to the disc-based version of the game, and how well it runs."
