if they add ads lets just not play it anymore

I'm always suspicious of games advertised as free to play. Yeah free to play except you don't get anywhere unless you pay for some kind of tokens to pump up your progress. Is this just another ripoff free game that forces players to spend real money to make progress?...

I built a small ship yesterday and now I can't access the small ship yard only to build the large ones. Has anyone else experienced this with the game??? I have so many parts and can't build any ships. I have restarted and all that stuff still nothing.

With normal gaming, do you need to purchase the premium to be able to upgrade to the full Shanghai tower? I wasn't able to get the full upgrade to the woolworth building, so it sits there unfinished.

I received a 'Promotional Ticket' after completing a freight order. What are they good for?
