Navagon: WTF?! Oh yeah, they really thought that one through! Seriously, what is it with GFWL and glaringly obvious oversights? Again I don't think that's the publisher's fault. Like the vestigial DRM that's been left in there. It's things they haven't been informed of that MS have buggered up.
Of course it's not publisher's fault, they even translated the whole game - and when first complaints came, they have apologized and at least provided way to unofficially screw GFWL over... While I'm at that, Microsoft actually seems to put more effort into securing GFWL from this kind of things than into making it work
