I know this would be quite troublesome to implement but I would love it to have difficulty and time to complete for games, both for games with achievements and without it. There's already a topic asking for HLTB, so that would solve time for majority of games, however difficulty is another story as there's no sure place to get this info from. Also for games with achievements it would be better to just have this as an extra set of information, and similiar to how PlatPrices does I guess. I would love to be able to order my backlog by those information
