Hi Simtropolis Community,
We appreciate your kind words about CityScape. We work hard every day to make it the best city modeling software available. CityScape is currently being used by video game developers, simulation developers, urban planners, and more. We would love for everyone who is interested in CityScape to be able to use it and we do hope that one day, we can make it affordable for everyone. When that day comes, we'll be sure to post it here on Simtropolis. For now, I can point you to some more CityScape videos so that you can see what CityScape is capable of and how to get the most out of the demo.

Regarding the comments about the building texture quality. CityScape ships with a default library of buildings and textures. As a developer, you can import your own library and use buildings with higher quality geometry and texture sizes. The stock library is built for both quality and speed. To support large environment, (CityScape can create cities in excess of 15km x 15km), it's important to save resources where possible. Though we have some amazing LOD technology in CityScape, this doesn't completely alleviate hardware constraints. I hope you understand. Some of our clients have produced photo realistic environments with highly detailed buildings when working in smaller environments.
Thank you for supporting CityScape. We'll keep working hard on it and try to get it in everyone's hands sooner rather than later.
