Something to keep in mind. First, this is just a game. If you want it to mirror choices, like in real life, then what youve seen already does that.
You smile at someone and say hello, or you dont. It in no way, shape or form means you will ever know how doing so affected said person. You might never know.
2nd. This game is still really early in it's development. Our feedback can be used to shape the next few releases.
But it still does not mean your choices will make tangible differences.
It could very well be you overhear a conversation. "Did you heat what happened to Miriel?"
Just my thoughts
