ShadowDust Software RPC.

A role playing creation utility by forum member ShadowDust702.  

Role Playing game Creator (RPC).  An IDE that uses gorgon for its graphics. It's also using Physics2D.Net, and Lua.

The goal with this project is to make a game dev kit that's as easy to use as the RPG-Maker series (If not easier), but with physics, render targets, shaders, particles, and Lua entity/add-on coding.

There is no limit to the size of the game you can create. Tile Maps are only limited by the amount of RAM on your computer.

The RPC website can be found here.

Asteroids of Beyaan.

A neat little asteroids clone by forum member Zeraan.

Britannia On-Line (An Ultima 6 remake... kind of).

A 'remake' of Ultima VI ... except as a multiplayer game using a slightly modified Ultima Online protocol and using modern game concepts (Double click to interact with objects, MMO like interface reusing Ultima Online assets, etc.) and enhanced art assets (32x32 tiles). 

GGCad by our forum member, gourky.

GGCad is CAD software that will generate G-Code programs for CNC (Computer Numerical Control) milling or turning. It operates differently than other similar tools, and the way you order shapes will drive the way g-code is generated. The overall philosophy makes it very fast and easy to use even if you do not know how CNC works. It supports either millimeter or inch coordinates, points, lines, circles, ellipses, arcs, splines (b-spline, bézier, natural-cubic, polygons).

gourky has also kindly provided the source for a scrollable user control for scrolling a Gorgon render window.  How awesome is that?

You can get GGCad from http://www.ggsoft.fr/index.php?lang=en.

Another, more optimized, shot of _kw's application.  Each pixel of the landscape is actually a sprite, and what we're seeing here is the landscape fully zoomed out.  Apparently, there's approximately 100,000 sprites being drawn (not every frame, else the frame rate would be very low).  Nifty.

Holy crap!  My first user contribution.

This is a world generator/editor by _kw.  From what he's described it sounds like a nice ecology simulator.
