Added a design document for zones. It has a design phylosophy that I think will work, and I plan to follow it for now. We will see whether it will be proven or disproven.

+# Zone Design
+
+This is currently the thinking I plan to follow on roughing out the first few zones.
+
+This is a high level overview on how zones should be designed.
+Note that art should trump these (like when things becomes monotonous, etc), these are just guidelines.
+Look at this as a staring point. 
+
+## Notes
+
+MMO = A Massively Multiplayer Online Game
+
+## Problems
+
+### I want complex MMO-Esque classes in the game.
+
+Levelling also actually need to serve as a tutorial.
+
+### The game should work well in single player.
+
+Levelling needs to be shorter than in MMOs, because it will be boring otherwise (MMOs typically make levelling slow, 
+in order to help people meet and quest together). However this makes traditional levelling slow and extremely tedious
+in a single player setting.
+
+This also means that zones need to be extremely big, and that you need to create tons of them.
+
+For example Vanilla WoW has something like 18 (Kalimdor) + 22 (Eastern Kingdoms) zones not counting dungeons and battlegrounds.
+Something like this is really cool, but unnecessary, and will not work well.
+
+### The game needs to support multiplayer. 
+
+Especially if the classes work well, it would be a wasted opportunity not to have it.
+However the game shouldn't be an MMO, as MMOS are designed in a way where you NEED to have certain numbers of players
+per server in order for everything to function properly, which is a big issue, if you don't have enough players.
+
+IF (and that's a big IF), the game turns out really good, people will likely want to have mmo like features,
+but that's out of the scope of this particular project, stuff can be reworked like that in a different repo 
+IF and WHEN the need arises.
+
+### World Scaling
+
+Since the game will need to support both single and multiplayer I'd say that world scaling (like the one in skyrim, and in WoW) 
+is out of the question, especially since I was (un?)lucky enough to see multiplayer player + world scaling in action in WoW. 
+It does not work well, especially not in PvP.
+
+Now there is a way to scale worlds, that I think will work in this case, which is a "new game +", or diablo solution.
+I think this will be implemented, especially before there is enough content to level a character, but even after,
+it will be able to give optional content to people that want it. It will be similar to Diablo II's difficulty, 
+except maybe it could go on for more (that could mostly be used for multiplayer challenges).
+It should not powercreep gear though (it should drop better gear, but only up to a point 
+- Also I think gear should be hand crafted -).
+
+Note that the World - Viewport separation in the engine is preparation for this feature + dungeons to be able to work
+on servers.
+
+### Levelling cannot be too fast
+
+Since I want classes to be complex, this means they will need to have lots of levels. (Not yet sure how much.)
+I'm pretty sure it will be 70-80-ish.
+
+If levelling is too fast, players either outlevel a zone without really being able to finish it, or
+if mobs are scaled to a levelling setup like this, then the end of a zone will be way too high level,
+and it will look awkward.
+
+WoW actually used to have this problem before they did the level squish, and levelling rework at the end of BFA.
+(To be fair, I think they caused more issues with the levelling rework, but let's ignore that for now,
+as it's really irrelevant.)
+
+### In essence
+
+The main issue is that levelling has to be slow, but not too slow, also the world cannot be just scaled around 
+the player like in Skyrim. 
+
+## The solution
+
+I think I came up with a base setup that might work.
+
+A normal run-of-the-mill zone should be similar in size to a standard MMO zone. This will give lots of leeway.
+
+A subzone is a quest hub with it's perimeter. Usually I saw around 5 of these in a zone in MMOS, 
+that I ended up messing with. Note that it does not really have to be a normal quest hub every single time,
+so it doesn't get boring.
+
+### Zone Setup
+
+The starter zone should level players from 1 to (around) 12, as the lower levels can be quite boring before you really
+start to have your class spells. This will have to be baked in into the stats.
+
+The next zone should level players to around 20.
+
+After that each standard zone should give around 5 levels (1 per subzone) if you can finish the entire zone in maybe an hour or 2,
+not counting optional dungeons. And of course not counting artistic variations.
+
+This would ensure that zones don't need that much gap in mob levels, while the thing won't get boring, and repetitive.
+Also less quests to create.
+
+This will get fine tuned when I get to it, but I think this is likely a good figure to be aiming at.
