Hi,
I really want a quest in the 3rd or 4th act, where we get to infiltrate a party. Having to go by our wits, conversation, lots of passed (or failed) rolls that will have an effect on how the party progresses.
I'm thinking there could be a "peaceful" route and an "assassin" route. So we would be able to persuade, charm, steal, bribe, blackmail or stealth kill guests as we saw fit. Have the guests react to the races we pick and let us be able to use our background. For example a high-elf noble would have an easier time navigating it than a Tiefling hermit.
Give us some different outfits to choose from (please a pretty dress and handsome doublet among them)
It would also be nice to have some romantic content with our chosen love interest; reactions to how we look, a dance and some witty banter.

I think it would be entertaining to have this setting where we can really dive into the RP and be as manipulative or cruel as we like.
