Here is an official list of missing assets that are needed badly in the game. Feel free to discuss in the comment section if you agree/disagree. This is not a wishlist since these mods have been requested before and no modders are up to the task. Ok this months nominees are:

10. Frieght Yard Buildings
9. Correct height grass foilage (trees category) Existing ones are so tall they tower people!
8. 1X1 cell grass square (prop category)
7. Procedural Overpass/Underpass walls
6. Manufacturing low-rise (flat top one story/two story large footprint) SC4 had ton of these!
5. Beer distributors
4. Turn Left/Right/Straight signs , but without the poles. To hang on gantries.
3. Modern Suburban Watertower
2. Bedroom community commercial (Dental ,Health, Sports Bars, Spas, Salons, eateries) These building typically have shingled roofs like housing does. Also think suburbia here.

1. LOW-RISE hotels! Were talking Spring Hill Suites by Marriot , Microtel, La Quinta, Motel 6, Fairfield Inn, Radisson. All have pointed roofs/shingles like houses and never more than 6 floors high! Another missing suburban asset I feel should have been flourishing in the game. SC4 had tons of these!
