I'm looking for a way to play the idea of the board game Junta as an RPG.
In Junta, you play a corrupt member of the ruling families in a banana republic, supported by various groups, ordering assassinations of rivals, changing loyalties quickly depending on who bids most and living a dangerous life between military coups and assassination attempts.
While I generally prefer systems with a focus on the narrative, I want the imminent player versus player to be supported by the mechanics, and I would prefer a system with appropriate mechanics for influence on population groups and military leadership, and close to no focus on the individual physical prowess of the player characters.
