Backlogs become pathological after a while, or pointless at best if a person doesn't actually use it.
My list started growing excessively so I started saying, "OK, just play [various games] FOR 15 MINUTES or a little while to get a taste." Then I delete them from the list if I don't really want to play them again or I've seen "enough". Many of them stay in my library even when I delete them from the backlog list, so it's not like they disappear from the universe.
If a chef makes food, you only need one bit to know what it tastes like. Games are art, programming, sound, level design. (Notice I didn't say "plots" in that list, since plots are irrelevant but an insecure gamer will use a plot point in hour #87 to claim that a person can't judge a videogame unless they played it for 87 hours to see the plot point.)
For a case where a person wants to think about a game(s) and not necessarily play it, which I think is more common than people consciously recognize, make a file of screenshots and notes/links separate from "backlog". A backlog is not a "don't forget this thing exists" file! I support appropriate records!
