Yeah. Everything I read said "ZOMG, this is the pirate game we've been waiting for for the last decade! It's amazing!" No. A pirate game where you can only swim for 15 seconds before you die, where you lose every naval battle, where a bird that humans made extinct because it was so underpowered kills you is not the pirate fantasy I was waiting for.
The build system is great. I wish I could do 1/50th of the customization on my ship that I can on my house. Really, setting up a pirate cove should be end game, not the first thing you do.
