Games
Faldon - Faldon is an online RPG I wrote, and am presently rewriting the client to (detailed in my Development Journal). The game has some flaws, but I encourage you to try it.
Useful Libraries
Apache Portable Runtime - APR makes it easy to keep a server portable, and provides has handy functions for safe path manipulation.
SDL - SDL provides an abstraction over video, input, etc., allowing one to avoid tedious low-level coding. On the other hand, its use of singletons definitely dirties all code it comes in contact with.
Squirrel - Squirrel is a nice scripting language. It's like Lua except done properly.
TinyXml - TinyXml acts a lot like .Net's XmlDocument class. For an XML library it's pretty small (140KB), and the speed is adequate.
Useful Programs
NSIS - NSIS is an installation program builder written by Nullsoft (the folks who made Winamp). It supports both BZip2 and 7-Zip compression and produces executables only a handful of kilobytes larger than a raw archive.
Programming Sites
lw-plugin - Go here if you have any questions about writing plugins for Lightwave 3D.
The Inner Product - This site has a lot of interesting ideas and articles. Sadly, it hasn't been updated recently.
Miscellaneous
Illumination Pit - Zammbi has lots of nice rendering art on his page. He's also a Faldon GM.
Spectre's Software - Aaron has a lot of good games and utilites here. Have a look.
Yet Another Blog - Crovax is a good friend and a GM on Faldon. This is his weblog.
