In Dungeons & Dragons, the player party will visit a wild variety of locations, such as old-school dungeons, a vampire's haunted manor, a dragon's cave, and far more. Back in civilization, the party may visit towns and cities, touring familiar locations such as taverns, a city hall, or even the local jail to question a detainee. But these locations can often feel same-y and forgettable, especially shops. No weapons or potion shop ever had the same flair as a dungeon like in Tomb of Annihilation.
