In my latest games, I always find myself taking particularly long to found my first several cities. When I first started CivIV, I told myself that 2500BC is a good time to found a second city. Any longer and you're at risk of falling behind in the early game. And I did an OK job of adhering to that. But now I find myself taking until 2000BC to get my second city up, and I'm just kind of struck that after all my experience I'm getting slower at this crucial aspect of the game. What I usually do is build a worker when my capital gets to size three and then a settler at size four (taking the time in between size three and four to build warriors, barracks, and/or archers). Is that taking to long to begin work on a settler? Should I start the settler as soon as my worker gets out, instead of waiting to grow another pop. point?
