What's the rarest game in your Steam Library? I might have a new one

How do you define rare? Not that I value my games based on how many people have them because I don't care but I'm curious.

The only game that comes to mind is The Last Remnant, but dunno how rare that is. Got a new physical copy with Steam key 2 years ago for 10€, I think that's a nice deal, and I just love these kind of games.

Was lucky enough to get a copy from someone for London 2012 olympic game, but there are some people who have Beijing 2008, even more rare. I played this one on PS2. Tokyo 2020 videogame is not really good. And there wasn't a good either for Paris.

The game i regret to have missed, it's ofc Fable 3.

How would I even begin to find out what is rare in my account and what is not? You would have to know of removed games in the first place I guess?

No idea, maybe Duke Nukem: Manhattan Project. Got it from Indiegala giveaway, GGD lists it as 100$. Edit: Actually probably Dark Souls PTDE 300$, found the tracker again.

I have Cart Life in my steam library, so probably that. some context: https://www.gamesradar.com/games/simulation/after-11-years-in-limbo-acclaimed-indie-cart-life-isnt-making-a-return-as-the-award-winning-games-remake-is-dead-and-not-suitable-for-selling-and-buying/
