When I bought the game, I was very happy to see a new smith city building game, with a simcity kinda look, but my first game was... I have to say the details and assets are awesome but the colours to colourful to a city, But ill touch that later
My Favourite part of Simcity was Specialisation Just creating an Oil industry (not just oil producing factories at a district)
A big Hq, business transforming into Oil & Plastic Stockholders, Banks, Corporation Skyscrapers and more, A Tourist Redoing
Make tourists more specific, They wanna go cultural they go to a monument or unique building, and the business will transform into Souvenir shops, Motels, Hotels, Travel Agencies. Make plowable working Hotels, don't make districts just industry wise, If Forestry is In, business would become woodcarving, furniture stores, Housing turning into log houses Etc.
Just make it more Focusing Las Vegas isn't the Same as New York not just because the skyline, the industry that moves both makes the difference, make Oil cities Dallas-like, Ore like Detroit, more models, more time and managing more fun
Thats my idea, If you have suggestions to enhance this experience please post, Im making a list
