I came across this website today and thought it was interesting.
It provides you with a good overview of how long it will take to beat a game: howlongtobeat.com

Also comes with box art, game rating and general overview.

Here is an example of an old-school favourite: howlongtobeat.com/gamebreakdown.php?game...%20Mario%20Bros.%203

That's very cool. I think I'll use it to help me decide the order in which I work through my backlog, which is some 30+ games deep at the moment.

If I have a couple of weeks with not much on, I'll pick a game with long completion time; otherwise I'll search for something I can plausibly beat in a timely fashion given however much free time I'll have.

Also seems like a feature people might like included on Archive.

Thank you so much for posting this. I was looking for something like this.

Many thanks this is a valuable resource!
