What would be really cool is if the listener could gain approval or disapproval from NPCS by voting in dialog options. There's already the ability to "vote" on dialog options. It would be cool if you could get approval or disapproval due to your vote. So, the person talking could choose option 1, and get disapproval from an NPC, while a second player listening in votes for option 2, and gets approval from that same NPC. It would allow people who are not playing as the party face to romance and build relationships with the NPCs in the party.
