I'm talking AAA games available on steam without having to run something like WINE.

I like games with strong immersion and narrative and on Linux that's restricted to Alien Isolation, the BioShock series, the Metro series, etc. and that's something which is rare on Linux unfortunately.

I, like many Linux users, have a windows boot partition just for games and the few Windows applications that I can't get on Linux I'd rather not have to do it but it is what it is.
