They've got a free game "Tinker" to download. Looks kinda neat, so I'll give it a whirl.
Though they kinda pissed me off. Just after I installed the update I noticed that my connection was being used, downloading something in short little bursts even with the GFWL client not even running. Turns out it turned the BITS service back on for background downloading. Hate it break it to them but I don't have a background to download from, so that crap can just fuck right off. Disabled it again.
