@cricket4103 You’ve got the point. All possible new features must not be conflicted with the existing content and rules.
So the region name should not be associated with contest, if it is people would freak out when doing a task. Probably it can be a part on City Information Panel or any other private types as you said. My original idea is to have City Name Signs for each region, Mountain and Landmark both fine.
As EA had proposed five regional maps instead of expanding capital area due to mobile hardware limitations, NEW MAPS could be their usual solution.Compared to a new regional map, Parent Map can connect regions in some form as one map to give us more of a sense of substitution. It could also focus on different simlulation priories and bring some brand new content that difficult to develop under the original map, such as Railway/Overpass Planning and Terrain Editing.
As a setup and control center, or to expand the gameplay? Here's more options for EA. I know that easy said than done and hope EA could bring us surprises if they hears it.
