Does anyone have a list of all the games they've beaten in their lifetime? This is something I'm very interested in. I feel like it gives a good indication of the experience people have as well as their taste. As far as I know I've compiled the complete list of my games beaten up to this day, though I'm sure I've forgotten some. I'll post mine below, and I encourage anyone else who''s interested in sharing to do the same.

Not feasible to do. Until SNES gen I was able to count the number of games I beat in the hands.
After PS1 I probably beat hundread games per gen.

I used to make such lists in the NES and Gameboy era as well as every game I ever owned and even some high scores. As I got older, such a list has become impossible. There are games that I buy now because I forgot I ever even played them. So I own them twice. An accurate list? Won't even try.

I'll just go by what I currently have entered into the "My Games" section of this website.  I only listed a handful of the sports games  There's a slew of annual releases I put time into that I can't remember by specific year.
