So I started this a few months ago, had to let up when school started, but my group has been working on it in full swing, and this is what we have so far
We want it to be a fun place for everyone, so we will be adding some scripts in like driveable carts, to get around faster, Food places to, you know, buy food, and little odds and ends for people to discover.
Currently there is disabled fire in every single brick (oops).
I designed the layout and built the actual building, all the offices are designed by different builders throughout the group. The current priority is the food court, then the rec. center, and then any open space, like the courtyard.
Love it!
A cool thing you do is have procedurally generated cars in the parking spaces, and have the same number of cars as there are visitors in your game.
