I’ll be using C++ with the SFML, and SFE Movie libraries.

For artwork: GIMP

Music: Perhaps some of the programs listed on the tools page here. Also perhaps a music generator  written by a colleague: http://www.omnimaga.org/computer-projects-and-ideas/pmusic-procedural-music-generator/

Plus anything else that I find I might need, but can’t think of/predict right now.

I am also using my own code base that sets up an MVC model for a game. I provide two versions, one with SFML already set up for use and one that is independent of third party libraries, so someone can use it with OpenGL, SDL, etc. I also provide an example program that makes use of it

You can download the code here, if you wish:
