PlayingTux is about gaming on and games for Linux.
About the Site-Operator and Main-Author: on PC I'm playing exclusively on Linux - since 1995.
At the beginning I've played a lot of DOS/Windows-Titles (thanks to WINE), but now almost only native games (thanks to Valve/Steam, HumbleBundle, GOG and a lot of others).
Thanks to Valve and Proton I can now also enjoy current Windows-only-games on Linux.
There's no game-genre, which I don't like.
