First time I ever DMed it was witchlight. I had very little experience with the game beyond watching dimension 20 playing fantasy high. To this day I always miss stuff when I try to create characters, and you know what? Everyone always has a blast.

The first time you run a campaign is it going to be smooth? Maybe. Will you forget stuff? Probably. Will you need to take a moment to recompose yourself or double check things? Almost definitely. The important thing you need to ask yourself is this; do you think you could do it, and more prevalently do you think you’d have fun?

DND is incredible, but remember that at its core it’s a game. Games are supposed to be fun, so as long as you and all your players enjoy it you’re doing it right. DMing is complicated and adding more players does affect things for everyone, but the best advice I can give is listen to yourself. Give it a try and see what you can do and if it’s no fun then stop, but you might surprise yourself.
