OnlySP: In 2007, Microsoft announced a new, online gaming service for PC gamers that people could sync with their Xbox Live gamertag: Games For Windows – Live. In theory, it sounded pretty cool. You could get achievements on PC that carry over to your Xbox, you could play with your Xbox friends on PC, and you only needed one username for the two. Some games even allowed for cross-platform play, pitting Windows players against 360 players. Pretty cool indeed.
