Adjusted the lua's map API, requiring a large rewrite

One the whole nothing major has changed, but I think this makes things
more logical. I just hope its stable, since I'm releasing a new tag.

-_This project is currently in it's early prototype stage. You can see other versions in various branches, tagged as prototype-X._
+The most recent stable windows build can be found [here](https://dl.dropboxusercontent.com/u/46669050/Tortuga.rar).
 
-Tortuga is a 3/4 top down multiplayer RPG set in a large archipelago occupied by warring pirate clans. The emphasis of this game is on multiplayer competition, exploration in an open world, and solo adventuring. The game runs on a Minecraft like server system with a goal of about 50-100 players on a single server. The player characters are tied to the server where they are created, and are susceptible to permadeath: deletion of a character upon death. The servers are designed to allow a large amount of modification by the hosts.
+Tortuga is an open source 2D multiplayer role playing game featuring permadeath (deletion of a character upon death). The emphasis of this game is on multiplayer cooperation, competition, exploration and customization. The game runs on customizable server software that can support up to 150 simultaneous players or more.
 
-## Libraries
+This game is inspired by classic 2D RPGs, as well as more modern sandbox MMOs. This project is currently independently created and funded, with the goal of creating a game that will engage user's imagination and inspire a large modding community.
 
-* [SDL](http://www.libsdl.org/) - Simple DirectMedia Layer API
-* [SDL_net](http://www.libsdl.org/projects/SDL_net/) - SDL's networking extension, slightly modified. This must be installed first.
-* [Codebase](https://github.com/Ratstail91/Codebase) - generic reusable code modules
+## External Dependencies
 
-## Instructions
+* [SDL 1.6](http://www.libsdl.org/) - Simple DirectMedia Layer API
+* [SDL_net 1.2](http://www.libsdl.org/projects/SDL_net/) - SDL's networking extension
+* [lua 5.2](http://www.lua.org/) - The lua programming language
+* [SQLite3](http://www.sqlite.org/) - A lightweight SQL database engine
 
-* This project uses C++11, which is available via GNU (or MinGW) 4.7, or Visual Studio 2012. Personally, I'm using MinGW 4.7.2.
-* I'm trying to keep this as IDE agnostic as possible, so if you use an IDE, please add it's files to .gitignore.
-* You can read more details on the GitHub wiki [here](https://github.com/Ratstail91/Tortuga/wiki).
