I've done so many proper maps, I wanted a change. Get away from worrying about gameflow and balance etc etc and do something small and compact and purely "visual" that only takes a week or so.
Yes, the images are big but my logic is that as I said before its a "visual" project. I doubt I will release this, the only representation of the map will be via the pics and panoramas and as such I wanted them to be large to get across as much of the ambience of the map as poss. I know that all sounds really "arty" but there we go
