Really nice! The layout strikes a good balance between organic and organized. I participated to a similar project but your output is visually much nicer than ours.
Are you talking about your TOWN? It is quite impressive! I'm considering porting my project to Unity3D too, because with Away3D I spend much more time on fixing some minor issues with 3d than on generation itself
Yes, that is the one! although it was a group work (I only did the buildings and filled the lots with them). We also had our share of stupid, time-wasting issues with Unity, but overall spent a lot more time in our generation code.
