Mostly this is out of curiosity - I find myself wondering a lot which the shortest / longest games are for a system, and right now there's no great way to find that out. This also helps me figure out which games I want to try to casually speedrun - I'm a lot more likely to try and learn a 20 minute run than a 45 minute run.

sitting at the top for fastest would be a lot of shitty games.

if you flip it you'd just get a lot of RPGs in the dozens of hours territory.
