I'm going to go against the grain here and say I primarily buy from Steam. A lot of indie games don't require Steam to run to play them and for the games that do, it's not hard to bypass. I just like having everything in one spot where I can redownload to other devices when needed, and I can have cloud saves for bouncing between my PC and Steam Deck. Also, if I nuke my OS for a 3rd time this month (changing distros), I won't have to start over on the games I'm playing.
