I started using Linux in 2008, and full time in 2011. I remember I could play natively to a bunch of games, like Dungeon Crawl Stone Soup, Neverball, Torcs, Dark Oberon, and others. I enjoyed those games, and I still enjoy some of them today. I think it was in 2013 when Steam announced it was coming to Linux, and native ports came too, like Braid and Dynamite Jack. Now, despite my hardware limitations, I can enjoy GTA IV, Stellaris, Prison Architect, Dwarf Fortress, The Stanley Parable Ultra Deluxe...
Things changed for the better, and thanks to Steam Deck, it'll keep changing.
