Hi. There are no premade scenes for now, only individual assets and prefabricated buildings. However it's a great idea, i'll add some in future updates
Thanks for actually listening to me! I love to contribute to new blender artists, if I have any problem with your package can I contact you? And also if you’re going to want to play the game with your assets you can follow me! My project is going to launch later this month and it will contain your city assets!
