Thanks Erik for the first answers.
I agree that the fact that Tiles.xml is not game dependent, makes things
somewhat more complicated. More seriously the automatic generation discourages
any manual adjustments.
I considered to define bonus which are tile dependent there, but that I think
I will drop that idea too.
Maybe the easiest path to follow for now, is to define any rules related to
the revenue calculation in a separate entity <RevenueCalculator> in Game.xml,
wait until the dust settles and if advisable move some functionality back to
more logical positions. That would decrease the coordination efforts.
The question about the token positions (be it open or used) was only related
to the graphical representation. I wanted to ensure that the path shown
travels through the tokens of the running company if there is one or through
an open slot, if the station is not fully tokened. Thus not really that
important.
