This is my take on the Sinnoh Region in Minecraft. I'm making the whole thing myself and am blogging the entire project at:
http://minecraftsinnoh.blogspot.com.au/
On this blog, you can see the project in much greater depth. Much more screenshots and much more for you to read.

Advantages of 2:1 Scale

What 2:1 scale means is that the Sinnoh Region in this Minecraft Project is twice the size of the Sinnoh Region in Pokemon on the DS. A 1x1 tile on the DS is 2x2 blocks in Minecraft. The advantage of this is:
- More space to walk around.
- More reliastic feel towards the original.
- Buildings can have proper interiors while retaining the correct exterior proportions.
- Much more detail per walking tile.
- Open feeling.

Accurately Re-constructed Towns, Cities, and Routes

All Towns, Cities, and Routes will be included. Every Town, City, and Route is re-constructed as accurately as possible. I'm aiming for as little error as possible. All hidden areas, buildings, caves, and landmarks will be included and have been re-created with top-notch quality.

All Buildings Have Interiors

All buildings will have interiors including all 8 Gyms, Pokemon Centres and Pokemon Marts. Plus all houses and landmarks.

The issue with the Pokemon games is that the interiors can be twice the size or more of the exterior which is physically impossible. Most interiors are at a 1:1 scale so that all interior elements such as furniture and televisions can fit inside the building properly.

Comprehensive Build Log with Screenshots

Every segment is featured in my blog dedicated to this project:

There you will find everything you want to know about how the Project started, Where it's up to and what's next. There are hundreds of screenshots scatterd around the blog so all angles are covered.

Where can I get this map?

The link is on the page in the usual place.

You will need Minecraft 1.8 or later to fully enjoy this project.

I'm using no texture packs as my intention is to combine the charm of vanilla Minecraft with the locations of Sinnoh. You can use your own preferred texturepack by all means.
