Someone should try to rank every game for real, though, that'd be neat, though obviously at least a few people are going to disagree in any case.
Though I can't imagine trying to get into the nitty-gritty of the difference of suckiness of the last couple hundred games (or more) not worth playing...I would probably have a bunch of them tied for last or make categories or tiers of games, with all those being in the "Not Worth Playing" section.
A lot of people say Friday The 13th was one of the worst NES games ever. I'm really surprised at that. There are surely lots of other games that are worse.
