$6122 (Sales prices) — $23198 (Total prices)
I've never purchased a game at full price and a lot of games I have gotten per bundles or for free/gifts.
So likely I would say....going by how much I paid for games on Steam since I started buying them...
I would say the figure is closer to $2,000 to $3,000 (this includes combination of games bought on Steam and off third parties like Humble Bundle, GMG, Fanatical, IndieGala, GamersGate, etc)
I've probably spent somewhere around that much for console/portable gaming as well in the same time frame if not more.
But between consoles/portables which I have been buying games for 25+ years I bought/received around 600 or so console/portable games compared to the last 8 years I've gotten into PC gaming I bought/received around 2,000+ games.
25+ years = 600+ console/portable games
8 years = 2,000+ PC games
