Games are meant to be played, not collected.

I'm not a gamer myself (the only game I ever purchased are a few chessboards ;) but as a book reader I know many people do buy books they will never ever read. They just collect dust on their bookshelves. It may be sad they don't get to enjoy the content, but it's their choice and there is nothing wrong with that.

I hope it's the loud minority that buys that many games. I think most people don't have the luxury to think that way.

You could just hide them and not complain about your "backlog". It's pretty unjustifiable but congrats on matching the thread topic I guess.

I fully understand not wanting them in the library. How I go about it is I have a category that's called finished, and when I finish a game, I remove them from all categories, except for finished, and then I hide/collapse that category. Alternatively, you can also filter by installed games.

I have a review for most of the games that I've played, but almost none of them actually count towards the game score because Steam has a really stupid way of deciding if a review actually counts or not. basically, for a review to count, you have to own the game or have refunded the game(I'm nit sure if deleting the game counts as refunding). And it must have been purchased directly through Steam. and it has to meet whatever Automated metrics they have in the background to decide whether or not it's a bot review or not.

I've had fully valid games that I purchased through Steam just not get included in the review system because something I sent in the review triggered some form of abuse system.
