Microsoft has announced that starting today, Games for Windows LIVE multiplayer features are now completely free. This includes achievements, TruSkill matchmaking, cross-platform play, voice/text chat, and friend lists. In addition to removing the "Gold" service fee, Microsoft has revealed plans to launch a Game for Windows LIVE Marketplace this Fall, which will offer downloadable game content (free and paid, determined by the publisher), demos, trailers and other goodies. They'll also be overhauling the in-game interface to make it much more PC-friendly, and reduce the technical requirements for developers. Click here to learn more!
