Apparently, all he'll make is $20. He forgets, there's a certain dupe method which can copy his program, as many times as one feels. Here's how it's done:

Player A boots up computer.
Player B boots up computer.
Player B buys MH for $20.
Player B goes into AIM and sends the file to Player A.
Player A uploads the file on his ftp server.
Player A releases the download link.

SHHHH!!! THIS IS BIIIG SHIT!! DOONT TELL!
