I’m sorry, but I’m sure you just said starting position was irrelevant (having previously falsely complained that you couldn’t change, therefore saying it is important) before then saying it was relevant anyway? And I’m sorry, but what is this over-world that you speak of? Are you just talking about the landscape, or is there some confusion there too?
The team haven’t actually defined their rendering system yet, but it may well be similar to MC’s. I’m not sure what you mean by seamless transition; chunks have to be loaded, and on even reasonable computers, you can be left waiting. Heck, on my Xbox I’ve waited plenty of times for a chunk to load to allow me to enter it. So SH would be very similar, were they to do it like that. Except it would be less important, as it is a city-builder and you really don’t need to venture too far away.
You’ll be happy to know that it will be 
What are you talking about? What is contained in this cube? Are you just thinking that it will be tiled, with each tile being similar to what we have as a map now? Because I don’t think that’s how they’re doing it.
Well, you’ve been looking in the wrong places. Here is the Desktop Tuesday where they talk about terrain generation, and here is a quote from it:
The terrain engine can tile land indefinitely
Ah see this might be behind some of the confusion. This is in direct reference to multiplayer, and not really anything to do with the terrain or its generation. This is about one of the multiplayer modes they’re considering, which would be that you could load in someone else’s city and the game would ‘stitch’ together they’re city into your world, from where you can attack it. It’s not to do with the tiling 
Surely then people just stop playing on that server? Seems simple to solve.
Well, your answer is neither. Dwarf Fortress is considered the father of these types of games, and there are others around, such as Towns or Gnomoria, or newly developing ones such as Castle Story. They all then put their own spin on it, and Stonehearth has not only put its own spin on things, but put in some absolutely superb graphics that none of the others can rival.
Well, a fair amount of that funding actually went towards Radiant being able to expand their team out to 6 people, as obviously man-power is somewhat expensive. Sadly, I haven’t played T&S, so can’t compare what’s in/completed as a system and not in yet (there’s quite a lot of stuff like that for Radiant, e.g. Infinite Terrain Generation)/planned to be in it, however with the funding I’m fairly confident Stonehearth can be more ambitious than T&S and ultimately have more content by its full release. Of course, this is all in the context of your disappointment at SH’s progress vs. T&S’s, I’m not bashing T&S here.
Can we please keep any form of company bashing down please? Microsoft have done plenty of their own things in their time. And, on your second sentence, not everyone’s stealing other’s ideas, someone has to be innovating. It seems a really cynical view and saddens me that so many people think like that. And, to be honest, when it’s a small thing, what’s the point of everyone reinventing the wheel? As a race, we only slow our progress by not allowing anyone to build upon our own advances.
