Another few quick comments on points raised in this thread:
- Religion - as has been mentioned, we are planning something here. The original SR2010 design had a complex religion model, but among other problems was the fact that it was, well, too complex.
. It just really didn't fly as a gameplay element. We've hashed out some plans to bring Religion back in a more straightforward way, so we'll have to see how that ends up working. We do understand that Religion is an important component in World politics and relationships, and we want to model that.
- Immigration/Emigration - We discussed this recently as well, and in general we feel that for gameplay this is not an area that works well as a 'micromanagement' item. Again, the original SR2010 design had lots of tweaking planned here (such as 'restrict immigration except for skilled', 'allow/disallow refugees', etc.), but all of that really had a very minor gameplay effect. One big change to this in 2020 is that the world we be a properly 'closed world', so that people will move between countries in a 'zero sum' sort of way. But we don't plan a lot of control to restricting immigration and emigration.
- 100 year games - We have noticed that some people like playing very
long games. So we've discussed what manners of death we can apply to leaders that stay in power too long
But we also understand that, especialy with the Sandbox mode, some people will really want a loooooong game, regardless of the tech tree issues. This is something we are looking at, and of course it involves a lot of elements (tech tree, AI, economic model, human lifetimes, etc).
