Not to go crazy with links, but this GameSpot column discusses the fascinating Gamerpoints system Microsoft has built into the XBox 360. There is nothing like competition to motivate people and bring out certain behavior...in this case, buying lots of games. And even with the highly-publicized shortage in 360 systems available in the US, games are just flying off the shelf at a rate of 3-4 per system AT LAUNCH. By now, that's probably up another whole game or two with the release of Oblivion, Ghost Recon, Top Spin, and other quality titles since the start of 2006.
