I switched to Linux a little before Steam came to Linux, and I made my Steam account pretty much as soon as it came. I’ve been here a while and it has been a wild ride. I went from mostly buying games through Humble Bundle (best way to find good native Linux games in the early 2010s IMO), to Linux native games through Steam, and finally to Windows games through Proton (I did play a handful through WINE, but it was always a pain).
It’s been amazing to see gaming on Linux go from something enthusiasts do to something that’s a mass market product.
