So I am looking to start a new group at my LGS. I don't have a personal group yet but hopefully I can build one after meeting new gamers. That said I have a serious question. I have the core rule book but should I invest into the Beginner Box for its extra content. I have several packs of dice already but I can always use a fourth of course but would the mini Core Rule Book in the box set be useful for new gamers? It would be smaller and it appears all the rules are the same with just less of the situational rules. Having the core rule book for myself I can reference all the more complete rules for my players but for basic rules isn't the beginner rule book just the basics and about the exact same?
Also do you have any advice for running a game in store with strangers? I'm thinking pre-gen characters and one-off mini adventures, or small scale adventures.
Thanks in advance.
