Today at the company's Build conference in Anaheim, Microsoft announced that Windows 8 will ship with Xbox Live built in.
According to Xbox Live's Major Nelson, bringing Xbox LIVE to Windows 8 is "part of our vision to bring you all the entertainment you want, shared with the people you care about, made easy."
If that seems like a very general and vague description, it is. Specific details are forthcoming, but I'd guess it means that developers of PC games will be able to utilize Xbox Live functionality within their games instead of Games for Windows. We should know everything about the Windows 8 - Xbox Live marriage when the Live dashboard update hits in the next couple of months.
My question to you PC gamers out there: Do you even want integration of Live within Windows games? I could see it being a great thing for gamers who play on both the PC and the Xbox, but only if PC game-makers take to using Live within their games.
