As someone who has dabbled for a long time, but been out of the loop for quite some time, I am really surprised to see how so many of the paksets have developed. I would like to throw out a suggestion here. Could we develop a page, that is an overview of each pakset ... that states where it is in development (playable, unplayable, playable with timeline off... playable from 19xx- 20xx). Wiki might be best for frequent updates. I'm still brainstorming the best way to do this...
Also should include what types of transport are included (eg... narrow gauge, maglev, monorail, 'mostly rail', few ships, no air).. etc.
I'm going to be getting some of the paks myself now... was happily surprised to see how far they have come.
