I have such idea for Witcher 4 called Wolf Triangle of where Geralt from Rivia will find Ciri from Cintra that went missing. Inspiration came out from Dragon Triangle. Eventually both Atlantis and Bermuda Triangle(it probably should be maybe even considered somehow in Cyberpunk 2144 including some sort of reference inspiration to Mariana’s Web).
As for Cyberpunk 2144 perhaps maybe CD Projekt Red might consider some sort of Easter Egg at least for instance as reference to both Plum Island and Long Island,but instead of New York City it would be Night City instead.
To save life of Jackie Walles to prevent his own death.

Wolf Triangle would be mix of both Alaska Triangle and Dragon Triangle a’la merge in The Witcher 4. As for Cyberpunk 2144 there could be references for instance to both The Elevator Ritual and Philadelphia Experiment maybe including Mariana’s Web informations about something similar to Bermuda Triangle. Including Easter Eggs of Camp Hero Bunker in both Long Island,Animal Disease Center in Plum Island as reference to the Montauk Project.
Eventually maybe something also for instance about Arctic Base,Dulce Base,Area 51 as reference to original Deus Ex.

Insert attractive women/men, as well as decent gameplay and plot.
Subtract literally anything a "consulting firm" says to put in the game.

Probably Witcher 4 could have Invisibility Cloak as for instance references to both Harry Potter and Predator including reference to Hollow Earth Theory(of where Geralt from Rivia would be fighting arctic creatures/monsters)as for Cyberpunk 2144 maybe there could be reference to for instance Stargate and CERN.

Well probably in The Witcher 4 maybe there could be also for instance both premonition and precognition as reference to Star Wars,healing with finger or arms like in E.T.. As for invisible flying vehicles in Cyberpunk 2144 it could be reference for instance to both Star Trek and Stargate Atlantis.

How about we make the next witcher have characters like the woman in Dustborn? They could just call everyone they come across racist and bigoted and whatnot. Oh wait, that stuff was already in the first games (Zoltan Chivay ftw) :D

Probably for instance telepathy,telekinesis in Witcher 4 would be very common reference to for instance both Dune,Harry Potter,Half-Life,Stranger Things and Star Wars. Maybe in Witcher 4 we could play both older & younger Geralt and Ciri as playable character for instance as reference to both The Legend of Zelda Ocarina of Time/Majora's Mask,Sonic Generations,Mario & Luigi Partners in Time. Maybe as for Cyberpunk 2144 maybe it would also have references to THX 1137(that White Room Tortures stuff),Squid Game,Half-Life,Stranger Things TV Show,MOTHER 3(Debug Room),Conker's Bad Fur Day,The Matrix original movie.

Maybe The Witcher 4 could have magic spell that enemies heads might keep turning into 360 degrees as for instance as another references to Conker's Bad Fur day,The Exorcist original movie,666 YouTube Channel. Imagine in Cyberpunk 2144 Jackie Welles inside The Elevator Ritual(somewhere in afterlife)keep saying Arriba Arriba Epa Epa Andele Andele likewise Speedy Gonzales as reference to Looney Tunes. I wonder if both Cyberpunk 2144 and Witcher 4 might have references to OOBE and REM Sleep Paralysis? Maybe there could be some quest related to both Arasaka Corporation in Cyberpunk sequel to asian girl that went missing in Elevator Ritual.

Dude, seriously. The pills the guys in white coats give you? You need to take them...

What kind of pills? What kind of guys in white coats? Do you mean Psychiatrists from Mental Hospital or not?

I started taking Vitamin B pills after visit from the psychiatrist.
Well as far as I know as far as I remember for instance I got bullied at both middle school and high school.
Anyway maybe in Witcher 4 Ciri might turn into female werewolf. As reference to Frankstein’s Monster and Project Moonbeam related to Project Montauk like something something radioactive piece of rock from Moon or Mars gathered by NASA(as inspiration),but instead of Duncan Cameron(as one of former US Navy marines)turning from human into Sasquatch there’s Ciri likewise Frankstein’s Monster some medieval styled scientist probably like somehow Calcstein from Witcher 1 survived or his spirit kidnapped Ciri started experimenting on her and she turned into female werewolf. So in duel or battle she can bite the other enemies and the other enemies might bite the others so she can use lots of sidekicks minions. And maybe Cyberpunk 2144 might have reference inspiration of some guy having Elon Musk’s Neuralink RFID Microchip you know so-called Scalie Easter Egg of humanoid amphibian.
Would corporate mafia replace politicians both locally and internationally or I hope that it's still not gonna happen?

This thread is the worst fever dream I never had.

OP given that the Witcher is a series by a Polish author, I highly recommend you read the original works to get an understanding of the world.

The Witcher series has its own lore and doesnt need to copy concepts from other IPs like Harry Potter or Star Wars, let alone parodies like Conker's Bad Fur Day. The Witcher has its own lore with external inspirations mostly coming from traditional fairy tales like Anderson or Grimm but with a more grounded perspective like how GRRM wrote ASOIAF based on a "grounded" perspective of traditional fantasy like Lord of the Rings.

The big challenge with Witcher 4 imo is that the world is losing its luster. Witcher 1 to 3 is set in an era where mystical beasts and monsters are becoming a thing of the past as humans are conquering the world. Witchers are close to extinct, spurred on by the fact that the method for the trials of the grasses is lost and there isnt that much demand for witchers and while a story with Ciri as the protagonist and leveraging her power both as a witcher and empress may be interesting (getting involved in both fighting and politics), a prequel setting where the witchers just started or are at their prime would be a different world that would also be interesting to explore.

Maybe at least Cyberpunk sequel might have some reference to Atlantis. According to Plato by quoting reinterpreting his own words Earth is not Orb,Flat,Concave/Conclave,Hollow,some sort of Dodakeadr/Dodaceadr. It’s Dodecahedron. In Cyberpunk prequel there was a hologram of Tikal Temple inspired by that one from South America.
