Which Games will get Removed from Steamstore?

Unless the publisher announces it before its removal, all people can do is guess.

Movie licenses, sports licenses, racing licenses, these are all things which expire fairly quickly so are bound to be removed from the store at some point.

The Removed Games Collectors has a thread for this subject. I don't know how they figure it out, but often if you're quick (and don't mind spending money on about-to-be-removed games) you can buy one before it's too late... :) Assuming you want to, that is. :) https://steamcommunity.com/groups/RemGC/discussions/2/496879865902369146/

Codemaster racing games tend to get removed after a while because their licenses expire

all games are getting removed, better buy 10 copies of each as an investment.

LOL

I don't know, maybe they will remove me next! D:

Legends of Aethereus was recently removed. It's page is still there, but you can't buy it anymore.
