Anyone playing none whitelist with steam play on Linux?

Hi there

So the whitelist is quite small, but I've see lots of other games (that aren't on the whitelist) work, anyone played or seen a (non whitelist) game working on Linux, if so, let me know

Ones I've personally played are

-Skyrim (not se)

-Operation Flashpoint Dragon Rising

-Age of Empires II HD edition

I haven't tried Operation Flashpoint Red River yet, but I don't think it will go well, because it uses the infamous GFWL extensively..
