I don’t think any CRPG is RP heavy. I don’t think it’s possible for a computer game to roleplay. Well, maybe if they integrate LLMs? But generally, any RP happens entirely in the player’s head.
I think CRPGs that are sometimes seen as RP heavy, are just very well written. That’s not the same thing, although I suppose it’s possible for good writing to inspire RP in the player. But that depends as much on the player as it depends on the writing.
I enjoyed the original VTMB a lot, mostly because of its excellent atmosphere.
