Spoiler :
I'm having quite fun with this map.

Built GLH, teched toward CS+machinery (through vassalage) and then toward optics.
Built a bunch of berserkers and galleys while caravels where on the way.
Hit charly and took just two cities before a peacedeal while teching toward liberalism.
Got astro from lib, and then the berserkers got turbo-charged.

Took 3 cities from pacal (and razed another), got ceasefire and then did a quick hit-and-run for two cities from toku who was in a dogpile against hammy+justantin.
Have sent out a few galleons with settlers to claim prime islands with 2+ seafood.
Once I had reinforced my initial berserkers with more, and backed them up with bombarding frigates it was very easy to kill pacal who was still at longbows.
Will soon upgrade to CR3 amfibious grenadiers and just run rampage.

GLH is so overpowered on these kinds of maps.
