I had an idea awhile back for a system where characters would be able to acquire social Influence points through role-playing events such as hosting a ball, or spending large quantities of in-game cash on “gifts”, or winning a battle, etc. These points could then be spent on influencing the NPCs of the world. Player social battles however would be resolved as 5 hands of Texas Hold-em with the currency being Influence points. No dice involved, but some real player skill with bluffing, betting strategy, etc.
