I've been enjoying it as it gives me the chance to build lots of base
Two minor gripes though:
1) People seem to declare war on me with alarming regularity (bad move Genghis, bad move)
2) It should be easier to get your workers to convert all your roads into railtracks.
Played it a little bit, seems pretty cool, I'm not sure if I'm playing badly, but the time seems to fly by really quick early on (The years that is).. and also boats seem to have a really small effect compared to previous Civ games? mm.. I will give it more chances as its some good light-hearted relief from games like CSS.
