Some good advice here, my extra $0.05 is:
1) Don't try and chew off too much at one time, especially with 6+ players (that's a lot!)
a simple, shortish adventure, with no expectations for a huge campaign, is actually a really good thing - you can learn a lot, make mistakes, then throw it away and do better next time.
2)don't take TOO much out of Critical Role - Matt Mercer is a great DM, but he over-does some stuff IMO, and the players definitely over-do the 'in character' drama. Don't feel you need to run a game like that, remember they are all Actors
Matt is a fair DM, is very well prepared, and also good at ad-lib (which comes from experience as well as preparation), take that as your inspiration.
So my friends and some of their friends are going to be starting a D&D campaign. There are going to be 6 of us with the possibility of a 7th (although, I really hope not.) Everyone is pretty much new to D&D have only played one or two tiny campaigns, if at all. I thought being a DM sounded like a fun thing to organize so I volunteered (because no one else wanted to do it.) I have never played D&D before and honestly I think it might have been a bit silly of me to agree but I'm willing to put in the the work for it to be good.
There's a lot of stuff in the DMs guide that you don't need. Focus on "Running the game" which surprisingly enough is not the first part of the book. As for the PHB pretty much all of that is relevant, but don't bog the start of your game with character generation - use pre-gens. If you're not starting off with LMoP (which includes pre-gen characters) then download some from WotC: http://dnd.wizards.com/articles/features/character_sheets
I have already started to read the dungeon masters guide, and after I'm finished with that I'll read the players handbook and the monster manual. I have also been watching some of Critical Role on YouTube and have been watching Geek and Sundry's GM Tips. Please let me know if there are any other helpful Youtube Videos or Articles that will help me.
I think you'll find the Starter Set adventure to be plenty long enough to make lots of mistakes and learn the ropesI am going to start us out doing one of the D&D adventure books. None of us want to do the starter set and we want a longer campaign. The Curse of Strahd looks really interesting and cool. Most of us would like to do this campaign but from what I understand this is not a very good for a beginner groupand a beginner DM. If anyone has any tips for us to be able to play this as our first campaign that would be great but I will probably do this as our second.
Actually, I'll even offer to do an Intro to DMing 90-120 minute session over Skype / Google Hangouts if a couple folks are interested. I've been seeing a lot of new DMs on ENWorld and I think something like that could be helpful.
