Some through emulation of some sort, others completely natively, because most gamer engines support Linux natively, making it trivial to do so. And as a gamer, I can't really tell the difference between the two.
If you mean Linux-only classic open source games, like Angband or Battle for Wesnoth or something, they still exist, but the demand has clearly gone down because now almost all games work on Linux. Except the ones with anti-cheat systems that rootkit-style access to your system.
Steam has been pushing Linux as a gaming OS, and it's working. Mainstream game support has come leaps and bounds over the last several years. It's still not quite as good as Windows. You will run into more bugs and have to fiddle with things a bit more to get them to work. It's improving rapidly though.
My only concern is that this is mostly just the result of one very influential company. If they turn evil on us...
