The other anno I played wasn't so much about building a city, but production lines. You had to set up trade routes from islands with natural resources to a hub to make a good, then ship those goods someone else to make a more complex good. Then you would use those goods for units and structures.
I'm not quite sure if that is a good move. If you choose the past you basically know how the stuff works and everything seems logical and fits together. That way you can concentrate more on the actual gameplay and make it work as fluently as in the past ANNO titles. But when putting your setting into the future you have to estimate more and you are more likely to make dumb design choices.
So i'm kinda sceptical how this will turn out, then again i am not a great anno fan, i appreciate what they have achieved with their games, but i never really played them.
The problem was that they had done pretty much everything from the past, they had 1602, 1503, 1404... 130 something or 180something would have been kinda boring I guess... Since there isn't gonna be much of a change compared to the previous one. Up to this point it has always been the graphics pretty much that made the difference, but they're already so advanced there that they had to think of something else probably.
Well, it's not like history hasn't brought enough intersting stuff they could make games about besides europe after 1300. Ancient egypt, ancient greek or vikings to just to name a few. Especially ancient egyp sounds really interesting , probably because it is a subject which gets picked maybe once in a decade. But then again, i am probably the wrong person to judge them because i just have a pretty vague idea of the gameplay .
