Whether this is a good gesture or not remains to be seen, all comes down to if they give us a choice over which game or not. Personally i feel this is a nice gesture if they give us a choice of any game with a limit of 800ms points, somehow i feel its going to be some really bad game no one would even buy if you paid them.
I was not happy during the downtime, took my profile over to a friends only to find when i came back i could no longer use it, tried to recover it to no avail, playing without my profile was just lame, none of my saves, no achievements saved and no xbl even if bits of it were working :/
