May be you can't program in C++, or draw graphics... There's other ways you can help... May be you just like video games... Retro-X will need game consultants to insure Quality Assurance...

May be you want to participate in the planning of RetroX... Or may be you want to design the levels for RetroX... There are many ways you can contribute to RetroX.

Or may be you like to write? You can create game manuals for RetroX... Or player's guides, etc... There are probally more ways you can contribute to Retro-X than I can think of now...

The point being you don't have to be a programmer; or a graphics artists to contribute to the Retro-X project.
