Yes, there will be Linux and Mac support as soon as 8 months and as
late as mid-2012. Our next major tackle (not that stability isn't a
tackle), so v0.3, is either traffic sim or multiplayer. However, we
already have a rendering structure from the 0.2 update to allow for
multiple API's (DX9 and DX10), so adding OpenGL support (so Linux/Mac
support) shouldn't be too difficult.
Now, regarding Wine, I'm not sure how our dependency on the Visual
Studio 2010 runtimes affects compatibility. Also, maybe this will
help, the only reason we have an installer and not just a zip is
because of our dependencies on DirectX and Visual Studio resources
which need to be installed along our stuff. If you can install those
two separately prior you should be able to just copy our exe and the
Resource folder to Wine and just run it (also manually create a
"Saves" folder in the same directory as the exe to be able to save
your cities).
And thanks.
