No reasons for this one. I had some extra money and I was bored. This incarnation didn't last long since all those diagonal walls and columns looked cool in theory, but were not very condusive for camera angles and screenshots. By the end of Gen 2 and the beginning of Gen 3- I had demolished and rebuilt. I did like some of the decor choices and a lot of that carries over to Reno 8.
In hindsight- some of these layout choices were....questionable. To say the least.
