Since the level design displayed in Tales from Candlekeep was inspired directly by the Adventure System Board Games, we decided that the dimensions of each tile would remain 4 by 4. In addition, we felt the need to add 8 by 8 tiles for the majority of the Villain (bosses) fights. In doing so, the visual aspect of the tiles feel larger and more appealing.
We wanted to keep a balanced level of difficulty similar to the board game in terms of monster spawners and gameplay ingredients.
In Tales from Candlekeep, the procedural map generation also allows every quest to remain unique even when replaying them multiple times.
