I'd still love to see us have the ability to recruit Scar (the main bandit encounter) as a regular lover or party member/roommate. He has such an appealing design and is a pretty interesting character. I'd also still like to see the ability to just...turn off women in general but that's just me. It is sometimes frustrating to get turned down with the dialog that suggests they're uninterested because of my gender despite them doing things at high enough lust.
Similarly, I'd like to see more with Gunnar. Being able to recruit or join him would be pretty fun...or a way to 'convert' him over time into being subservient to us. Would be interesting.
