mine would go something like:

stuff i got just because it was cheap: 983785789567

I have 25 games on steam so I don’t need to organize them
I joined steam in 2009

“Uncategorized (250)” sums it up pretty well

Newest trending game tag in steam Craig-like and Craig-lites.

Not pictured: Won’t make the mistake of playing with Craig again

I need me a Craig.

I have mine set up with a bunch of categories that are sorted with a prepended 3-digit number. Allows me to have different sections of category without it getting mixed up. ex:

010 S
011 A+
012 A
013 A-
014 B+
etc...
350 plz play soon
355 wont play
...
800 dont remember buying this

I just use dynamic collections, eg. group games by their store-tags, eg. arpg, fps, puzzle, walking-sim, online-coop… etc, whatever I consider handy when going through all of it.

Sure, the categories have a lot of overlap, but I don’t mind, the games list is a disaster anyway (>1300 games on account… yea.).

I used to maintain my own categories, but at some point the number of games started to be too much to do it by hand.

edit: One of the better features is to group games with online-coop with friends who have it too. Makes it a lot easier to find the next adventure to start after few beers.
