So, I was looking through my normal waves of gaming sites when I saw an article whose title I thought might peak your interests. It was for a map on the Source Gaming Engine(The one that Powers Half-Life and Counter Strike) that was made to look like the adventurer's club.
I don't know how many people own the game or know how to insert maps into their games but I'll post the YouTube video and some instructions on how to insert maps.
I'd recommend that anyone wants to do this use Garry's Mod, which can be purchased through a downloadable gaming platform called Steam. It can interpret all Source Map files and is by far the easiest way to work with the program. Unfortunately, Garry's Mod requires the purchase of a separate game from the Source Engine to work. Here's the page for the purchase(remove if its not allowed to be posted) for the game
