MAPS & MATHS
For various reasons I'm shy about publicly posting wips too early in the process. However, in this case I think it's warranted - for those curious about why it takes so long to make a map of this ilk, and also to give those less experienced in the specifics some insight into the kind of things we consider when designing a a playable map.
Most of the chunks are fairly straightforward to do the initial resizing with because they either connect to each other in ocean areas that are easy to cheat (losing or gaining a few water tiles has a relatively minor effect) or by pushing into the Steppes (which need to be vastly shrunk anyway).
Africa is tricky. Not necessarily in terms of techniques to apply, but tricky to get a good result in the context of the overall map.
Even in this low-rez relatively undetailed image you can see that reducing Sub-Saharan Africa with a simple vertical resizing leaves the continent looking like itself. Below it is Europe enlarged to the desired proportion. So far so good.
The problem comes when trying to match them up. Unlike North and South America where the Isthmus is a single flexible join, Africa is anchored to Europe at three strategic points: both sides of the Strait of Gibraltar must line up, Sicily & Tunisia need to be close together, and the Levantine coast is more or less a straight vertical. As you can see from the image on the right, simply stretching Africa just doesn't work: beyond undoing the changes that reduced the less desirable areas, it's inelegant visually
and mathematically - which creates too many game-play issues to list in a brief post.
Not that it's necessarily a conceptually difficult problem. It's one of those situations where the solution is relatively simple but requires careful consideration throughout a process consisting of quite a few painstaking & time-consuming steps. The ultimate result will probably involve some creative distortion of Europe that doesn't spoil the overall effect or adversely affect game-play. 95% of the work involves breaking Africa apart into a lot of little pieces, doing all sorts of geometric manipulations (resizing, distorting, rotating, transforming, etc.) with them individually, adjusting them relative to each other as I go, and as I do so also making sure that when the puzzle pieces are recombined it looks good and plays well.
I've been through a similar process before - manipulating Tibet, the Ganges Delta, and other outlying areas to make a South Asian map. So I know already what to do with the world map and how to do it. It just takes a lot of time - and the time devoted to it requires a certain kind of focus and energy that can't be turned on as simply as opening a water tap. To be clear: I enjoy the process even though it's slow.
If nothing else, now you know what's going on even though there's no wonderful wip images to post. Yet.
