Junk
Patient Gamers
A gaming sub free from the hype and oversaturation of current releases, catering to gamers who wait at least 12 months after release to play a game. Whether it's price, waiting for bugs/issues to be patched, DLC to be released, don't meet the system requirements, or just haven't had the time to keep up with the latest releases.
Vendor Trash
I always called it "clutter" tho I don't know whether this is in any way official. De-cluttering an inventory means tossing the useless stuff out or packing it away.
Tchotchkes?
"Tchotchkes: A knickknack or trinket; a decorative item or souvenir of little value." <-- This isn't bad
guff.
Guffipedia was a gold mine.
Vendor trash
"Mathom" - A trinket or piece of bric-a-brac; a knick-knack, often used in regifting. Term coined by J.R.R. Tolkien
One more word to add to the collection: cruft. Stuff that just builds up without you really noticing, mostly because it’s easier to collect everything than to filter it out of the good stuff.
Clutter, misc, trashure, junk, scrap.
Dungeon Lint
Bad game design?
