This isn't really a suggestion or request, but should we be expecting more regions per time period at some point in the future?
I mean why, for example, don't we have "Abandoned Towns" from the other time periods?
The original thought behind this was that each continent should be divided in to regions before it's divided into time periods, by which I mean, the map generator assigns an area as a "city" or "forest" or whatever which is then cut into the different time periods, which I think would help both the feeling of it being an actual continent and the feeling of time being fractured. but obviously most of the regions required for that don't exist. Also I couldn't find out whether the world is supposed to be fragmented in space as well as time, which would sort of throw the idea out.
As an incidental point, because I was looking at the continent map too much, I also noticed that there are no rivers in the game, though admittedly I can't think of a way to put them in the game in a way that makes sense. perhaps just background art.
