UPDATE: I recently started my first Emperor game on G&K after getting used to the new mechanics on lower difficulties. I've taken on board the advice provided above but in my current game I'm concerned that I'm not going to achieve a victory condition before the AI does.
As always, I'm playing as England. It's a small continents map (regular settings, aside from legendary start). I have taken Liberty and Commerce as I was planning to gold-focus (with a wide empire) as I have had some really fun gold-focused games in the past, especially in the late-game. I'm most concerned about Russia (yep, she's in my game
yet again!), Rome and The Netherlands who have the most territory, largest military, tech lead etc.
To my advantage I am on an isolated continent (save that William has settled a small city to the west). I was sharing it with Sweden but conquered their two cities by around 500AD. I think that this was the right move to make as they were trying to settle another city and this would hinder my own progress. However, conquering Sweden appears to have had a knock-on effect on my tech and victory because I had to pump out units to finish them off. I am currently 3rd in tech (I was much lower) even though I have NC and universities in my larger cities and am struggling to catch up, although the extra spy is helping. I have also had to cut back my military due to low gpt - it's only two gpt now.
I planned to go wide from the outset and I currently have 7 cities (one annexed; 6 settled). There isn't really any more land to settle so now I have to conquer.
Here's my problem: It's 1640AD (turn 238). I am behind in tech so cannot take on the AI with a few advanced units and I only have 2gpt so cannot afford to buy/produce numerous units.
I know I need more cities and trade posts to get the gold coming in and I need libraries and universities for science but to get more gold I have to slow down on science and to get more science I have to slow down on gold. Russia is about to launch an attack on my frontier city (see screenshot 3) and will surely go for my main continent later.
Now, do I:
(1) Turtle up and hope that I can get a tech lead and win a science victory?
(2) Go on the offensive and hope that I can win even with inferior tech and no money? (This may or may not lead to a domination victory)
(3) Turtle up and go for a cultural victory? - 7 cities is arguably too many but there is a chance. I am allied with cultural CSs and have +134 already
(4) Keep building, defend when necessary and worry about victory later (and hopefully improve the situation) - this is what I am currently doing but I am halfway through the game and need to focus
Any advice is most welcome. Btw, I have really cut back on those wonders now (I've got 5 world wonders, one of which was Sweden's). At least happiness is not a problem!
