HOW MANY GAMES DO YOU OWN ON STEAM

I currently have 287 games in my Steam library. In addition, I also own a total of about 100 games from Origin, GOG, Uplay and Epic Games, and some games on CDs (yes, they still exist, and they are still a thing.)
Nonetheless, no matter how many of them I have, I probably played about 15 of them. Of course, sporadically I tell myself that I have nothing interesting to play, even though I have tons of games that I never finished, or games that I simply didn't have enough time to complete. In the near future, I'm going to go through all of my games, and finish all the games that I never had the time to play.
