I tried for achievements, but once I'm almost done with last civ, it got too tedious and wanted to end it sooner and not bother with puppeting entire map. Also I don't think my machine can handle it and it was already starting to run slow.
Start was insane enough that I was able to do a GL start, got every wonders I bothered to build, and was able to rush frigates before starting war. Obviously tradition since I wanted to focus on my one city. Later went patronage for extra science as well as commerce, rationalism exploration the needed. Ended up Order ideology since it would give more immediate happiness.
1. Buy city states with MOV's - 1 point for every CS purchased, maximum of 5 points. 6 if done in 5 different eras. Only generated 3 MoV total since I wanted to get GS, so 3 pts
2. Puppet the whole map - 5 points (6 if you never raze a city personally) No where close, except I did not raze a single city.
3. Obtain 9 or more Great Galleas's and keep them alive until the end of the game (They can be upgraded). - 1 point for every 3 surviving Great Galleas, 3 points possible
3 pts, never lost a single frigate and I ended with more than 20.
4. Make MAD Money at some point during the game (500 gpt - 1 pt, 750 gpt 2 pts., 1000 gpt. 3 pts.
Pretty easy and I didn't even need many cities to get 1k gpt. 3 pts
5. Build Colossus and Petra in Venice for extra trade routes - 2 pts. each, or capture them while conquering and get 1 point for each.
4 pts, built both, pretty easy with insane start and actually focusing the tech for it.
Bonus Achievement. Annex a city - 1 point ?
13 pts
