My personal retro-backlog, which basically consists of most of the well-evaluated, relevant and popular games of all time, from each year of launching, I've sorted them manually using Wikipedia and Backloggd. Besides having a huge list since 1972, I'm playing them using my personal system of 1 game per year, to have things more dynamic and versatile, when I reach 2000 (for now, at least), I'll come back to the first year with at least one notable game, and advancing through time again. Although I'm using this system, I try my best to respect famous franchises' chronological order of playing, so I won't play Super Mario 2 before the first one is beaten in the past. I'll be feeding this list as I will playing them.
