I played through the whole night and not even begin to discover all that is new. ANNO players are really required, so there is a new chain of high-tech suits where the final product of 20! Goods and 10 buildings there. For that alone I needed several hours. Oh, so far not a bug I noticed.
What ADDONS nowadays come herraus with such a scope?
People who like to want to get upset over a bad game and deceptive and must get rid of their frustrations in order not to suffocate, which I recommend Bus Simulator or so. That really has nothing to do with a good game.
I rate the game with 5 stars and not the company's policy or package descriptions or otherwise.
