If you want to play in the Forgotten Realms Campaign Setting, then this map is a must have. Mike Schley has done an amazing job in capturing the Realms in this truly huge and beautiful map. Yes, there are some areas that are not there; this is not a map of all of Toril. But it works great if you want to create a campaign around the Sword Coast and the Savage Frontier.
Mike Schley has done some really amazing work for 5th edition D&D, but this takes the cake in my opinion. I plan on printing it out on canvas and hanging it on my wall.
