Including the Amiga in a Multi-platform release i.e. using portable languages (C/C++) and re-target-able graphics routines (SDL) can earn a bit of money. (I dunno if you divide the number of hours by the amount you get minimum wage?)
Someone has released two commercial games for the Atari Falcon (Windows, Linux, MacOS, iOS and Android) recently.
