Three+1 friends, three+ years.
------------ b1.2 - 1.7.9 ------------
With "chunkboardercliffs" and weird biome mashups etc. caused by algorithm changes through updates to newer versions of the game.

Randomly revisited
---- 1.10.2 - 1.12 ----
Thus strangeness appeared in form of disappeared chests, broken portals etc.

Most of the time played and built with John Smith textures.

This is a reboot of my old Secretbase map (https://web.archive.org/web/2020/http://www.minecraftworldmap.com/search?s=secretbase)

I udated it to Minecraft 1.7.2. You still will need mods to play it but it's less than before.

This map is complete. In Minecraft you will find a book that explains everything.

*****Mods needed******

Make sure you download the mods for Minecraft 1.7.2
