Love the guide - have it bookmarked and refer to it often.

Have a suggestion regarding new cities. How about a guide to where and how to build them. I realize there is no hard and fast rule to this, but some guidance to those getting ready to build their 2nd city would be good.

Close to your first or really far away?
What's important to build first, second, etc.
And the answer to my biggest question (just can't find it anywhere) - do you have to research everything again??? for your new cities or does the research share across cities? If so, is there something that needs to be build to a certain level to share? The thought of waiting another 256 hours for archery 10 just makes me angry.

Thanks for the help!!
btw - I miss your duck.
