You have a point, but isn't the score you receive by a win also dependant on the other persons Charisma or something? Because I can swear I've had RPS matches with my 4 in Charisma where a win has only awarded me 2 points.
In the end, the whole RPS thing is fun but too easy to cheat since you can just quicksave, press space and quickload until you get your way. It was fun for my first playthrough where I just let things happen and never reloaded, but once you know the different outcomes it's hard not to cheat the system. Making Charisma largely a waste. I wouldn't have minded if npc-related dialogue was simply decided on your Charisma vs theirs, no rolls or mini-games, while dialogue between the two main characters used the RPS system.
