In Coup: Rebellion G54 (G54), the last player with influence in the game wins, with influence being represented by face-down character cards in your playing area. Before each game players choose five character roles from a randomized deck. Characters have a unique variable power, and the deck is formed by three iterations of each role for fifteen cards total.
Coup: Rebellion G54 is a new standalone game that takes the same simple Coup mechanisms and rules, but with a variable deck of 25 characters, and in each game you choose to play with five out of the 25, so the relative power and advantage of each character changes from game to game.
This is more of a gamer's game than the original Coup as you can create a deck to increase bluffing, deduction, negotiation or luck.
