I just recently found out about the programming language Lua. I can’t believe I hadn’t heard of it before, but apparently it’s used as a scripting language by a lot of game developers. Supposedly it’s used in World of Warcraft, Grim Fandango, Escape from Monkey Island and other. There’s a .net bridge for Lua called LuaInterface. There’s a port of Lua to the PSP, and a port to the Nintendo DS. There are a couple tutorials on using Lua with C# and .net here and here.
