Does anyone have any more info on his involvement with Drake? This game is pretty infamous, especially in the gaming youtube sphere, and this is my first time hearing of null's connection to it.
Doing some googling IMDB is the only site listing Josh as a writer besides a few film databases which clearly scrape it.
Most list Stefan Ljungsqvist, an art director on the Just Cause games, as the only writer.
Googling "Joshua Moon" "Drake of the 99 Dragons" and other variations of Josh's name yields no results with the exception of a few garbage text amalgamation sites.

I tried looking for the credit sequence, but remarkably it appears no one has bothered to do a longplay of the game. All letsplays seem to omit it as well.
At the moment I'm leaning towards this being inaccurate information. Either some other guy who shares a name or some troll who thought it'd be funny to attach his name to a notoriously bad game.
