An interesting comment on the CSL forum.

From co_emmi:

Maybe more CIM modding? if possible

This is something we are looking into at the moment.

Is this CIM2 or CIM1?
I hope its CIM2. I would to see CIM 2 come back to life as it was never fully developed.

I sadly think they don't meant Cities in Motion, they meant the CIMs, the citizen of our CO-games.
I would murder someone to see a third game. Maybe with procedural building generation, there is a lot room for improvement.
Played Skylines mainly because of the public transport options. First I paint a beautiful city, then I strap over my public transport network..
