Brilliant! Absolutely brilliant! Sure, there's a lot of room for improvement. For example, the sphinx's head could be more 3D, and there is a lot of empty desert, but look at it this way: There are chests in that desert that contain useful items. It can also be used to hide from other players. And remember: The map isn't set in stone. There will be updates, and some of that "useless desert" will eventually become towns filled with cool buildings and traps! Have you criticizers even seen the system of sewer tunnels spanning the map? You can get anywhere taking those. And the Pyramid! The Underground City and the treehouses in the Jungle Kingdom! Pure artistry! This map has some serious potential, and after some revision and updating, this map could easily find its way into a Community Map slot!
One suggestion though: Could you make an alternate version with a Host House in the Pyramid and redstone-operated starting platforms (like in the original versions of Vareide's maps)? Doing so will make this map available for use on servers that don't have the Plugin, or simply prefer the feel of starting the Games with a lever rather than a command (like the server I plan to create). Thank you for creating this amazing Survival Games map!
