When it comes to designing locations and buildings, the DM/GM has a much more daunting task ahead of them than most players or even the DMs themselves realize. Thankfully in most of the RPGs we play and run it is far from crucial that the design of the world is 100% accurate and entirely believable. Most players are willing to suspend their disbelief to an incredible level and almost all DMs don’t really have the time to make sure every location they put into their game is believable. However, creating an environment that is believable can actually make your players lives easier because they will buy into the game on a more unconscious level. This added level of believability just might turn out to be the whole new layer of depth that your game needs.
