How 'easy' was it for you to become a gm?

For me, the challenge was by far, learning to create campaigns that were not just fighting monsters.



I was never a railroady, asshat, or adversarial gm.



But man, when I started out, my games were combat focused.



Fortunately a player told me "Bill, all we do in your game is go into dungeons and kill monsters. Where are the Imps selling magic trinkets? Where is the rivalry between the local priests and thieves guild? Etc.. Etc..."



I wised up fast.
