Maybe it doesn't matter to you, but many people buy/play games for gamerscore. It's crazy, I know, but people actually legitimately care about a little number next to their name, a 64x64 icon of an achievement, or the top 10 spots on that leaderboard. It sells more games, it keeps engagement higher, and it is all around a powerful platform piece for Xbox, as it will be for iPhone, as it will be for Windows Phone.
