2nd Prince game - where did I go wrong?

Had a quick look at the game and a couple of things stand out for me:

1. Biggest thing is you probably should've built more workers. Your cities are working a lot of unimproved tiles - that makes a big difference. And Rome has a non-specialist citizen. Why? At the very worst you could put that citizen on a plain and get another food without losing the production. Antium has marble (I'm assuming that's partly why you put the city there) - did you never hook it up or did it get pillaged?

2. In particular you have very few cottages - you need those to keep your science up, especially since you have the bad luck not to have any rivers around.

3. There's a lot of forest just outside Rome's city radius. From the map I'm guessing you've choped forests only inside Rome's radius; chopping the ones outside gives you the instant production boost without hurting your continuing production accumulation.

4. Neapolis and Cumae are both one square away from the sea. Not usually a good idea: You have sea resources in your radius but can't build a lighthouse to use them properly (though that probably won't have had much effect so far - something that makes more of a difference later in the game).

5. You built the pyramids, so why didn't you change to representation? That gives you 3 happiness in all your cities, with your current civ size, and extra science from specialists. (Though in your current war state, democracy might be better to help you rush-build units).

6. It looks like you've only just founded Neapolis a couple of turns ago. Since you knew you needed the iron urgently, why didn't you put the city next to the iron (or on top of it - even quicker, but less production bonus)? And have you really only just discovered that iron 4 squares from your capital? Either you weren't scouting enough early in the game, or you left researching iron working till too late. (High priority if you don't see any copper once you have bronze working!)

7. Why did you research sailing when you're in the middle of a continent and have no coastal cities?
