What are some things you would like to see a sort of spiritual successor to?
Not a remake or remaster or rerelease of something old, but something inspired or influenced by something either popular or a cult classic. Also this could extend to hardware/tech too, not only media.
The game series Thief is the defining experience of satisfying gameplay for me, and there are not enough games like that. Stealth as a core mechanic, with the expectation and ability to entirely avoid combat and detection, a first person perspective for immersion, and a fascinating fantasy setting and story.
The closest to a spiritual successor is the Styx series, but it's been a while since the last one was released, so I wish for another game like that.
