I see a lot of screen shots with roads or rails on every open square.
I know in civ you got a commerce bonus for roads and rails which made it wise to have every open square have a road on it. So far I have not seen this to be the case in CTP2. Am I missing something? do roads and rails in ctp add anything except a faster way to move?
No, roads/rails/maglevs don't add commerce bonuses anymore. Not sure if they did in CTP1 either. Made this mistake my first game untill I noticed that none of the AI opponets used roads except where they needed them. Then I checked both a road and non-road panel of the same type and the commerce amount was the exact same. Was none too happy about that seeing as how I had an entire continent covered with railroads.
