OpenGFX => I haven't read the license so far, so I don't know what would be the restriction. I'll check it at some point... but I would love to avoid looking too much like TTD, to give a more smooth look
Name => Not really, for now, on my computer it is called IMT for "I'M a Tycoon" ... but I don't really like the name
I'll search for names once I have something that I can release for alpha/beta/whatEverA
Mechanics/Balancings => Tough question, I have some ideas on how I want to do it (which I won't go into detail at this point). But basically, a player cannot assume both role (mayor and tycoon), you will have to choose what you want to do. Obviously, one role will have an impact on environment and other players job. As the picture in my head is very complicated, I will go step by step with first implementing the transport side, then production and finally city governing ... and most probably, I will have to continue integrating aspects such as corporation and government, but by then I will have either stopped the project (due to its failure or my lack of interest) or the game will have already be released...
Look at the game "Starpeace" It aleady has that aspect figured out.
Btw I have a 27 page google doc full of ideas for this game, of which i would call Impetus™
If you make a game of this scale into an MMO, then you are basically creating a new reality for everyone. lol
You might check out the "http://stateofprofit.com/" project and see where he is getting held up (Time).
ALSO, if http://empire.goodgamestudios.com/
can do it smoothly (HTML5?) Then I think we can pull off our openttdmmo. lol
I think the only way to truely make this game epic is to seperate it into different spans of time, Each player starts out as a single cell and works their way up to commanding a galactic empire (spore).
And, solely paid for by adrevenue from my youtube channel, we could distribute Impetus™ for free!
