My wishlist:
1. We need a breakthrough. We don't need the grid. I know it's harped on but yea no grid 2. I'm eager to see what the acrologies would look in in Simcity 5
3. I know this may sound kinda stupid but what if we got some sort of futuristic city on our hands? Hey, teleportation comes useful when you need it (Though costly )
4. Seasons. Snow in Singapore 5. Full 3D
6. Advisors that you can pick. Not a game function but rather more like a eye-candy.
7. Region terraforming.
Yea that's about it.
