The sewage map I must agree is pretty crappy. Bermuda Circle on the other hand was a genuinely good romp. It was definitely lacking aesthetically, but played quite well, and would score quite well on the RS scale in my opinion. Personally, I'd ditch the sewage map and focus on improving BC.

Although the architecture and texturing (especially in Bermuda Circle) are lacking somewhat, all the fundamentals are there. I suggest revamping the maps in VML, both are reasonably lackluster.
