Just call me the DEMO guy.
Really that is a brillant idea though. Have David make up a DEMO disk cover and those interested in doing so can download the demo, burn it to disk, print the disk cover, and take a few copies to local gaming stores to give them for free. I haven't seen this done before.
Or perhaps shrapnel could print up a demo disk that has all of their games on it and send those to game stores. People get the free demo disk play the games, and voila, you have sales.
