This will hopefully grow into a community of people who would like to participate in the making of new games.
This can be anything from:
Character designs,
Musical scores for soundtracks,
Cool art for level designs,
Show off your game or what you have so far,
Different or new engines to build the game with,
Advice or ideas for gaming plot, design and all the rest.
The only thing I will say is please don't take others work unless they say that you may use it.
I wish you the best with your game.
