We were right. They aren’t free. The 7 games that Major Nelson stated would be free using the XNA system, aren’t. They are all 17-day trials (what a rip) and you have to have an active subscription to continue playing after awhile (this is an XNA subscription [$60 for about 4 months]).
To play XNA games you need to download the XNA Creators Club Game Launcher. To access the games you need to go to My Games and move the the XNA Creators Club. Then press Y to download, play and stuff. Supposedly to download you need an active XNA monthly subscription.
