OK so I've been talking a lot about Polynesia and I decided to revisit them a few nights ago to really put my money where my mouth is:
This was an interesting victory for me because I experimented with a few new things without the expectation of actually ending up on top
Victory: Defensive Diplomatic
Social Policies: Liberty all 5, then Commerce all 5
Map type: Large Pangaea (that's right, I wanted to fool around on their least favored map type)
I ended up with 7 cities total - all of them built early on. All coastal cities. All within very reasonable distance so it didn't take long for the borders to meet. I was fortunate to have at least one sea resource per city, with the exception of my capital (2 resources) and 7th city (3).
I struggled terribly with gold/production early on because I made the idiotic - but completely intended - decision of spamming 7 maori warriors just to see if I could manage them. Typically when I'm trying to win defensively I never do something like that - I just really wanted one warrior per city...just because. With the help of commerce, I did manage. Little did I know that having those maori warriors ended up saving my ass. And here's why:
I settled my 7 cities way too quickly and that pissed off my neighbors. Ethiopia attacked but I had a more advanced army so I was able to hold them off. Unfortunately 5 turns later so did Korea. And their army was way better than mine. But, I'm telling you, with any other civ (non-combat related civ) and I would have been pupated in a heartbeat. I was just able to hold them off, without a single casualty and with many of my maori warriors (upgraded at this point in the game) in the yellow or red health.
If not for the -10% enemy effectiveness UU bonus + the 10% UI bonus (20% total, essentially), I would have been wiped out. I was trailing in tech and I was lucky to have survived. I ended up winning the game on diplo because of mad cash from Commerce, trading posts and of course moai. I only managed to build one wonder the entire game (two if you count United Nations), and it ended being the one I needed most: Himeji Castle. That's 15% combat bonus added to the -10% in enemies and 10% from moai. That's what allowed me to actually breathe, since England and Japan later joined in on the Polynesia whipping. Thank goodness I allied myself with the right pair - Sweden and Persia, who distracted a lot of my enemies and allowed me to win in the first place
On a side note: Sweden keeps dominating in my single player games lately, this one included. Anybody else have them doing insanely well as AI or is it just a few strokes of coincidence?
Edit: Bolded key words for those who just skim the long posts
