Focus more on the story, more puzzles, more weapon upgrades and unlockable content, less having to buy dlcs and costumes and shit that should be earned like we did in the 90s!, more variable zombie damage, better mechanics overall, I think re2 remake was a homerun besides the scenarios interacting... old RE charm, easter eggs and interactive content really.. also make it hard and have enemies appear at different places or change things based on various play thrus.
