Now on to Domination (which I am terrible at, and have not done even a single 3 star game yet).

My basic strategy template used was to go for Diplomacy and lots of early tribe contact. Generally don't attack other tribes or trespass when possible. Put embassies in the distant capitols first, the tribes won't interact with you much, and the relationship will improve. You can stay on one city for a while, don't worry about expanding, you're just getting the stars per turn from Diplo and improving relations, teching up, building improvements, top-tier units, etc.

Pretty soon you'll have more or less friendly neighbors, who with a bit of luck, fight stalemates amongst themselves. In general you want the AI to fight itself as much as possible while you arrange your troops and then break peace. Breaking peace gives such a huge advantage to the attacker you can often take out a civ in a turn or two.

Focus on maximizing stars per turn by using custom houses (or whatever your civ has). Combined with Diplomacy these will essentially act like compound interest. At this point you're just conquering your neighbors as quickly as you can, which is easy since the AI is dumb.

As for temples, I generally don't bother with temples unless I am already super far ahead. I focus instead on maximizing improvements for each city, choosing Giants at first but then Parks once victory is assured, which is usually the better option. Towards the end you're just stealing all the AI temples and wonders, and you should hit 100k no problem. :D
