Fable 2 & 3. The original is but not the sequels for some reason.Fable 3 was on Steam but it had to be delisted when Microsoft's old "Games for Windows Live" marketplace was shut down in 2013. Unused keys can still be redeemed and used on Steam. I bought a working Steam key off of Amazon back in 2020, but I'm not seeing any listed now
Also all Nintendo games obviously
