A few beginner DM questions

Hey all!

I’ve been a longtime fan of this game and fondly remember playing this game with my uncle as a teenager. About ready to start running my own game and looking for some feedback from more experienced people.

I’m planning on running the advanced version and starting off with the premade adventures. Once we complete those (🤞) might start writing my own, but curious about adapting the original’s (basic) adventures too. What to watch out for? Or are the differences pretty obvious?

I’ve also been reading about Karma rewards and remember it being one of my frustrations as a player. So, if we could keep it civil, I would like to read your thoughts/opinions on this to make a more informed decision for my game, please.

In time, I hope to repay your kindness when the next person comes asking for help. Thanks for reading and responding (hopefully).
