Over 1300 on Steam alone. Mostly from Humble Bundles / Humble Monthly / Steam sales. I don't think I've ever purchased a full price Steam game. I went through a period of working away from home and not being able to play many games for several years, but I kept getting games I wanted to play if they were on sale and wouldn't go much cheaper in the next few years after purchasing. Only just now made a start on my backlog. I built up the collection over several years but it's great because when I think "Oh I really want to play this game" I go to check Steam / PS Plus / PS Now / Gamepass etc and there's a good chance I own it and had no idea.
