Re: [Rails-devel] 1862?

Mike:
great proposal to volunteer on 1862 ;-)
As 1880 not an easy one.

However in general I think targeting the newer titles is a good idea, as 
they are more likely to be played and usually they are not supported by 
Lemmis moderator.

Some comments below.

As I mentioned before on this list, I intend to change the Round 
mechanism to use mechanisms based on compositions/interfaces instead of 
the current sub-classing approach which in fact exposes everything of 
the parent class as an interface.
However this will be 2.1. so feel free to start with existing approach.

 From my first reading of the train rules it seems that there is no rule 
which is impossible to implement with the current calculation mechanism.

The current implementation already allows trains based on hex-distance 
(freight trains). The other train types are also supported.

Running all trains independently, but counting stations only once will 
be achieved by changing the network graph. You will have each station 
included multiple times equal the number of trains, but only once it 
will have a non-zero score. Using "vertex-visit" sets ensures that only 
one of the nodes per city will be connected by each train.

The various rules that apply to the intersection of trains and visiting 
tokens will be checked by a dynamic modifier which sets invalid train 
run combinations to a zero score.

However I agree that 1862 without it is already an achievement.

Go to 2.0. I am currently merging and picking from the various branches 
for the alpha release. After the alpha release (from later today 
hopefully) please use rails_2_develop.
