Some of these maps seem unpolished, or have other flaws (like simply being too effing huge); on the other hand, some of these maps are fantastic, and the architecture and geometry overall is fantastic, if not overwhelming. A must-have just for the cool visuals alone, but a keeper for some solid maps.
This is the fist map pack that i've circulated widely. My focus on this pack was creative architecture and over the course of 3 major revisions i've gotten the flow of these maps up to speed as well.
