Im thinking on a indirect way to monetaze on rom hacks and game mods, make a site with the rom hack or mod you made, then when people go to download a specific item they download it, and then you offer them "the complete rom hack" with a report about a topic relevant to the item. Example: lets say you have a hack of wizards and warrios 2 and want to make a hack that changes the hero head for that of Fabio's (The warrior in the cover art of the game) and call it Fabio's Edition. You change the heroe head and helms, make it downloadable, then you present them whith the "complete version" with a more dramatic change to the hero, armor, weponds etc. and a pdf report on a topic relevant, like aditional ideas how to make the hero look like Fabio in diferent ways, a comic, poems, relevant trivia; stuff it with as much relevant content as possible and you charge them for the report. Any improvements in the idea are welcome.
