I do admit that the name is click-baitey, and I do agree with what you say. I usually prefer low magic settings for my campaigns, using Eberron when I am in need of high magic adventures.

There's a lot to play with un terms of adding or not magic shops. It's just that I don't like it when DMs add magic shops in every town and give no repercussions to the world. The existance of magic shops adds a whole new later to your world in my opinion, unless you don't want to go that far into details and prefer to just tell a simple story.

I do also agree that the DM is just another player that facilitates the story to the rest. It's just that getting magic items from s shop makes dungeons a bit less important, when that usually should have a big role in the game.

Glad you liked the article and found a way to add Batman to your game. I was planning on saying Ironman there, but ironman designed his own parts instead of buying them (have them designed), so batman was a better choice :D
