very buggy indeed. And they locked a feature that was free to an old DLC again (canals), gg PDX

Edit:
Now after 3 patches the game at least seems to be playable again. Canals were made free again as well. Now to rate the actual new DLC content:
- Favors: The new favor actions sound cool but were turned from OP to basically useless and in general rather seem like bad mod than worthy DLC content
- Concentrate Development and Pillage capital tend to lead to massive cities which is just very unbalanced
- The currently existing monuments are cool, but there seem to be far too few still (especially since for me they were the main selling point)
- The new colony types are a nice idea but I'm not quite sure what to think about how they did it, since they are basically the same as before just with a different base modifier and the possibility to add quite a lot of bonuses additionally that last basically until the end of the game, which makes having a lot of colonies pretty OP

Edit 2:
I've decided to come back to this about 2 years after the DLC.
Over the patches many more monuments have been added to the DLC so that I feel that the amount is now at a good level. The balance problems with concentrate development have been fixed and it's a mechanic that has its uses from time to time. Bugs from Leviathan have also all been fixed by now, afaik. Hence the review has been changed from negative to positive now. Probably still a good idea to wait for a sale though.
