How to add a removed game from Steam to wishlist ?

javascript:AddToWishlist( GAMEID, 'add_to_wishlist_area', 'add_to_wishlist_area_success', 'add_to_wishlist_area_fail', "1_4_4__40_1", 'add_to_wishlist_area2' );

Perhaps?

I asked in a previous thread here, but wasn't able to figure it out.

it's not possible to add to your wishlist

• delisted games (no store page) https://steamdb.info/app/105400/
• unavailable games (store page with no buy button) https://store.steampowered.com/app/437220/The_Culling/

At least not anymore

Why would you want to - the game wouldn't be visible in your wishlist anyway.

It used to be possible, but back when Valve updated the wishlist (which broke it in a lot of fun ways, which is why I keep having games randomly vanish from it and haven't been able to adjust the ranks on my wishlist since the update went through) they removed the ability to add removed games to your wishlist.

Not only that, any previously removed games you may have had on there also got removed, which was a real slap in the face to those of us who were using our wishlist to keep track of those games (eg, in hopes they'd come back onto Steam, or to remind us to try and hunt down remaining keys, or similar- but, even more relevant to SG users, the wishlist was a great way to track when such games were posted to SG for giveaway).

TL;DR version: Valve broke it™, as usual.

you can do so though Barter.vg if that is any help they have most all removed or band games on the site
