If you play games like Mass Effect, Dragon Age, The Walking Dead or so on, I have an idea for you.
Instead of making choices, let a coin decide the fate of characters, what you say in dialogues and so on.
I found it to be a fun way to play games, the problem is games with 3 choices like The Walking Dead, there you can use a number generator from 1 to 3 and the number that pops up is the choice you pick.
Just an idea though, hopefully you like it
