I finished a game I had in my backlog for over 20 years.

My oldest back log game that I own (disregarding a whole bunch of C64 games) is Snake Rattle ’n Roll for the NES.

I’ve never been able to get past the second ice level (ironically I think it’s one of the last levels of the game I think). Great game tho, but it’s probably 15 years since I last played it.
