A lot of valid points have been raised and I haven't got anything to add at this moment, but I would want to clarify that I was NOT advocating to 'dumb down' the game. As I said in the first post, I too am eagerly awaiting the next version. And as said before I do believe the new version will be great for most players here, who already have a firm grasp of the game's workings.
What I meant to do was simply start a discussion on the topic of complexity and, as the thread title says, on how much is too much when it comes to future features and the threat of featuritis.
I think the most important point raised several times is one I failed to consider at first, but totally agree with; if the interface evolves at a pace that is in line with the game's complexity, doesn't need to be any problem.
In response to Mechanoid: In a way complexity DOES add to difficulty. Perhaps not for the people who understand the way the game works, but certainly so for new players, especially if the complexity grows faster than the methods of handling that complexity. If you have a dozen easy tasks to do, they might not be so easy when you have to do them all at once, especially if some of those tasks spell certain doom if you do them wrong. For an experienced player it's easy to keep a lot of plans in the back of your head about what you need to do and when, but to a new player it only adds to the confusion. As said before, that isn't so much of a problem when the method of handling that complexity is adequate, so when the interface gets properly revamped the new features will be easier to deal with, but added complexity without proper means to control that complexity DOES increase difficulty. Also a point of advice: Unneccesary CAPS LOCK usage, swearing and 'tl;dr' tags don't exactly make you look intelligent...
