First of all I would like to thank you for your great work, you are awesome!
Unfortunately, I don't know about the technical requirements for a port, but would it be possible to bring one of the Stalker parts, preferably "Call of Pripyat" or the open source standalone "Anomaly", to the quest, or if necessary PCVR? I think the engine isn't developer friendly but I think it's one of the best horror survival RPG games of all time and it has a huge modding community. I would love to play it on the Quest.
