I have installed the demo version. And I don't think the controls
and tutorial are as bad as is often claimed. I've seen much worse.
My biggest problem is that I usually can't categorize the numbers
correctly: For example, what does 16,00 mean for the bus driver?
Does that mean that a bus driver earns 16.000 a year? And what
about the vehicle capacity: 26 passengers for a double-decker bus
or for a stretch bus? At "Cities in Motion Collection" is a screenshot
with the VEHICVLE SHOP where you can see this problem. Has this
been changed in a game update? Or is the game deliberately
designed this way and you have to calculate a factor of 2 or 3 yourself?

I use Pentium Dual Core E2180, GeForce GT710 and 2GB RAM
on MX-15 Debian Jessie 32 bit and the demo version works fine
with Wine 1.6.2-20.

What do I get for a version of Cities in Motion when I buy it here at GOG?
Is it the same as the demo version 1.0.21? Some claim that there are
much newer versions of this game. In the GOG database for the game
I read that version 1.0.21 German has been removed. Is the game now
only available in English? What about the Linux version of the game?
Is it now available here on GOG? And if YES, will it work for me?

Do I buy a Windows version of this game here at GOG although GOG
warns me that it is not suitable for my operating system and then,
unlike the demo version of the game, the game really doesn't work?

There is now a rating and a short review from me on the store page.
I bought the game.
The Windows version of the game works perfectly for me using
Wine 1.6.2-20. I play the game with a resolution of 1024x768
on a 19 inch monitor and have reduced the graphics settings to the
minimum. You should know: I use a computer from 2007 with a
graphics card from 2014. But I am completely satisfied with what I see.
The display quality is perfectly adequate for me!

But the most important thing is:
Despite all the flaws in the game, I like this game!
