With the Mapuche details released, I can now decide which of the builder civs I want to start my playthrough with, unless of course Shaka has decided to give up his spear in favor of a pen
I have to say even though I want to start with a builder civ, the Mongolian music is tempting me

Thank you
@Thormodr for mentioning it!
Korea, Scotland, Georgia and the Dutch are very tempting for me to start with. Scotland has a fun amenities bonus and golf courses, and I like their concept overall. The Dutch have those awesome polders and culture for international trade routes. Georgia has a great turtling vibe and subtle bonuses. And finally, Korea has the Seowon and it'll be fun to jump ahead in science, as well as their minor governor bonus.
It's a tough decision, but I think I'll go with Korea. I'll try to balance between picking up more governors for their bonus or promoting existing ones. Looking for good spots for Seowons, to surround them with farms and mines, should be fun. I usually enjoy picking a civ and trying to use them for a victory type that they're not typically geared for, so I might try a cultural victory. I'll probably get Amani as my first governor to try and go for a nice suzerain bonus.
There are quite a few vanilla civs I want to try too with the new mechanics. Looking forward to it!
