> (Braid, in 2009)
Braid had already made a pretty big indie-game splash in 2008 on the Xbox 360 as part of Xbox Live Arcade though the PC release was in 2009.
I was lucky enough to have played it before the Xbox release back in June 2008 on PC as a beta tester (Jonathan Blow was on the quartertothree forums and recruited testers there in the run-up to the Xbox release, iirc).
Apparently I was using Windows Vista at the time because some of the bug reports I can see in old emails are about how Braid's DirectX fullscreen mode was broken in Vista.
