Try Victoria Isles World. Beautiful Ocean Vistas, no routing errors so far, I've been using for about 6 weeks, mostly building so far. My sim is an architect and I realized most of the homes were too perfect, and I also decided to check out all lots, both new and those included, before I play them. There is about 11- 64x64, 9-60x60, 15- 50x50's and much more. Fully updated all rabbit holes etc. Many Victorian Homes, beautiful I might add. Of course you can bulldoze to your liking. I used "Add Lot Size" program, and got many more lots. I've tried quite a few worlds and cities, and nothing compares to this for me.
