Just want to tell you about a small OpenSource development project available at my site.
After fiddling around with lots of extensible extension languages like Tcl, Python, Windows scripting host and several LISP dialects i finally used "Lua" for some projects at my job.
Since Lua gave me the biggest productivity boost i decided to contribute to this OpenSource project of PUC Rio.
Lua also was used in some successful games like my current favourite game "Baldur''s Gate", Grim Fandango and some current titles of BioWare (MDK2) and Criterion studios.
Due to its fast bytecode, small footprint and dynamic extensibility Lua is the ideal tool for RTS and RPG game - especially for implementing NPC AI.
My contribution is EDELUA, a comfortable source code browser / inspector you can embed in your games as VCL component or ActiveX control. There is a lot more to say, if interested read it at:
