The interesting part about Cities 2 is that the simulation is much more in-depth: pops have a real job where they commute to (versus taking any available one in the first game), they don't just teleport around, companies have to import&export resources and make profit based on that, etc.

Also the graphics/lighting seems much improved with a more realistic art style.

Both things which you cannot really retrofit into Cities 1.
