should be in the base game, not as a DLC.

Good bit of content, but very little of it. 10€ for leviathans is a salty price for what it offers, if this was part of the Utopia DLC it's asking price of 20€ would have been easier to justify. Worth getting just to have more content in the game but paradox is really stretching by asking money for this little. Could/should have been a free update really.
