We're 13 sessions in but I can easily put it anyone into the story without ruining the narrative. If you know Fallout its a plus and if you're chill and really get into your characters, then you've found the right group. The 4.0 PnP is not difficult to understand and I can provide the link for it, or just google it. DM me if you'res interested. I also stream it on Twitch just as a heads up.
