I would be interested in doing some cooperation in getting a game done. I am however pretty inflexible in the tools and technologies used, at the moment if I was to work on a game project I would insist on:

Language: Delphi (also keeping in mind FreePascal compilation)
Graphics: SDL using OpenGL
Sound: SDL_Mixer or OpenAL

Most likely using Reiners Sprites

I was thinking that the Dragon Flight game I wrote actually has a lot of potential. There is a market for vertical shooters out there. Most shooters are space themed and a fantasy themed one like Dragon Flight may catch a slightly different market.

If you (or anyone else) would be interested in trying to get this to work (or anything else with me) register yourself on my forums and lets talk about it.
