City-spamming is still ingrained in my play from years of previous Civ games, but boy it can get rough in BNW, especially if you want to play peaceful. With the science/culture penalties and national wonders, you take an early hit that you don't really make up for until you've got a bunch of happiness from buildings or religion. Plus other civilizations get super aggro when you forward expand.
Any decent guides or let's play videos for wide liberty opening strategies?
