A cool idea for a future game (sequel or spin-off) could be a modernised, urban version of PQ where you play a descendent of MC after years of industrial revolution & technological advancement. I would imagine something like Castlevania LoS 2, Shadowrun, or Eborron. Greyport would expand into a greater city, with Weirdwood becoming a city district (like alot of modern cities), & many races have either integrated with Humans (Halflings, Elves, Dwarves & Giants) or live in the war torn regions outside the major cities (Goblins, Orcs, Ogres & Trolls).
The city of Greyport would be a dark & dangerous place where Thugs, Assassins & Killers stalk the streets. The sewers are infested with monsters & critters, while, ferral dogs, giants rats, oozes & other dangerous pests lurk in the back alleys. Knights now have energy swords & behave more like a mix of frat boys, sports teams & rich jerks, & Guards would be closer to modern cops, while nobles are just the super rich with titles. Beyond the "safety" of the cities is a Fallout/Stalker/Metro-type wasteland of blasted badlands & petrified forests after a great war. Here farmsteads struggle to maintain a livelihood as greenskins, beasts & monsters stalk the land.
The Descendent (MC) is the last remaining member of the bloodline after the Purifiers hunted them all down for their heretical nature! You're mission is to defeat the Grand Patriarch of Light & restore you're grand bloodline by breeding with as many women as you can

. I imagine the Lord of Light' religious order being like a mega-church version of IRL Catholicism/The Vatican as its own religious political power house.
I know this idea will most Likely never happen for this series but I thought of it today & decided to share it here.
