I'm building a role-playing system and am just thinking about the social skills.
In D20, you have like appraise, barter, intimidate, gather information, and then the really useful diplomacy, bluff and sense motive. In some other systems, you have lots more. I also thought about just using Charisma and nothing else. But after all I would prefer having 3 or 4 with everything captured within, as this would be the nicest solution for my system, as I use relatively broad skills with possible sub-concentrations you can pick (for example firearms, with handguns, rifles, bows, ... as concentrations).
I want to have a few as possible that can be combined as well as possible. I thought about one manipulative (barter, bluff, intimidate), one representative (diplomacy, entertain, "first impression") and one investigative (appraise, sense motive, gather information), but I don't like calling them Manipulate, Represent and Investigate.
Do you have better names? (Bonus: do you have a better idea for how you could split up social skills?)
