how to install

I wish my F2P ass didn't destroy my seal mask

nvm the items when you use a pass are not tradeable as well
i dont know what items you could swap for the no longer obtainable 4 or 5

i would swap some items though
make the stuff that you get when you use a pass non tradeable and make the seal mask,super monday night items and black rose tradeable in this change instead
but you dont have to do that

All of the items that are tradable minus the Manniversary Hat are already marketable.

honestly if that means that they can be listed on the market then that would be great
also YES!

Most of the items you listed are distributed by Valve so I decided to make them limited similar to the Finder’s Fee.

The Three A promos will probably never be restocked as the manufacturer of the figures have since gone a massive restructuring. As for the other physical item promos, I assumed an item that hasn’t been normally available in years has been phased out of production.

At the end of the day, Valve selectively applies what changes they want to add from my submissions, if they decide to go through with them at all.

Saxxy, Memory Maker, Wiki Cap and the Unusual Cap aren't exactly limited, as they can still be earned. I'm mostly sure that all the Limited items in the game are items you can no longer drop, purchase, uncrate, or receive via craft or anything else other than trading or selling/buying from the community market.

Exceptions to the first ever batch of hats introduced in the game, where they can still be found on their associated crates, however, such crates no longer drop, making them limited in a way.

However... Finder's Fee is technically not limited, as anyone who finds a game/economy-breaking bug, or security-related issues, may still be granted one, despite being marked as "Limited".

Robo-Sandvich and other Genuine-only items may not have been marked as Limited as they -may- sell them again, but I'm just speculating.
