Anyone claiming that software is defective is probably trying to lie their way to a refund. /QUOTE]
Hold on there, compadre... I bought both batman games during a steam deal and both are very broken on windows 8. Granted, that's not steam's fault directly, but that information should be available on the front page BEFORE I buy the game. Non-refundable.
This isn't a steam issue, this is a GFWL issue - i've read similar issues at the rocksteady forums. All GFWL games are broken in windows 8; this is unbelivable when considering that a Microsoft product breaks another MS product. You'll have to do some shenanigans to fix it, I remember reading about this somewhere.
I'm pretty confident that the fault lies entirely with the publisher and developer, for using the god-awful piece of garbage that is GFWL for DRM. That's another issue with GFWL, it's a 3rd layer of DRM on top of steam to deal with. If the game were just steamworks, this would be a non issue.
Bottom line, GFWL sucks. And I actually fully support refunds for all GFWL games, although it should be done by Warner. In the mean time, I will *never* buy any game using SecuROM or GFWL. I personally only purchase steamworks games. If it's anything on top of that, DO NOT BUY.
