This development worries me. I've seen this happen before.
This new science system brings complexity and detail, but to no great effect on the actually gameplay. The skills it gives geologists are effectively just permanent buffs. Did we really need an entire science tree of additional buildings to fit on our islands, just to achieve permanent buffs to specialists? I suppose it's one way of doing it, but it smacks of complicating things just for the sake of it. Surely the same skills would be more logically achieved by specialists through accumulating experience. If my geologist has searched for the same copper mine a thousand times, don't you think he might have got a bit better at it after a while?
I don't want to pre-judge, but I'm worried about the direction things are taking. Did anyone ask for this? I've seen lots of requests and suggestions, but no great clamour for what it is we're being given. If all the development is going into new tech trees and complexity, rather than new adventures, new content for high levels and fresh challenges that will keep us interested for more than the couple of days it will take to learn a new tech tree, then I'm not hopeful for the future. Sorry to be a bit down about this, but I really have seen this sort of uncalled for and pointless complexity be introduced in other games and it didn't add to the experience. I hope I'm wrong.
