Golgtron recently checked out the new GFWL update and decided to play some Tinker.
Golgotron says, "The greatest thing about Tinker is that it is completely free to play. Tinker is also exactly the type of game that you would expect to see on XBLA. I actually wish the game was on the 360 so I could play it on my TV as well as talk in a group chat over LIVE. I will say, however, that Tinker is a good sign of what is to come to Games for Windows."
