Alright, point taken. As Radium stated, this may be a total flop. Everyone should be aware of the following before they get involved:

1) This is not going to make anybody money. There will be no compensation (other than your name in the credits) for any work done, as the game will not be sold. The most that will happen, if the game turns out good, is I will pay to have copies made and sell them at cost+shipping.

2) There is no guarantee that the project will make it past the early stages. I will promise, however, that whatever does get completed will remain publicly available to all.

3) Because of the nature of the project, any work you do (art, music, levels, etc.) can be viewed, updated, or replaced by anyone else. The idea is for the group to make the best content possible, not for individuals to own certain parts of the project. No one wil 'own' any portion of code/graphics/etc.

4) This is a learning project. More than anything, I want everyone involved to become collectively better at what they do.

That said, here are several talents that are necessary throughout the life of a game (obvious stuff first):

Programmers (in varying areas of expertise)
Artists (still and animated)
Musicians
Level Designers
Writers
Translators
Storyboarders
Marketers
Game Designers
Architecture Designers (defines how the code will work)
Quality Assurance (testers)
Site Administrators
Forum Moderators (don't everyone raise their hand at once)
Tools Developers (build systems, version control, etc.)
Graphic Design (logos, CDs, advertisements)

...the list goes on. Don't be discouraged if you can't program and don't know how to draw. There's much more to be done.
