Well I dont know the specifics of your situation but here's
my advice. I've written a couple commercial games as have friends of mine.
Writing scripts for Lynx games brought up to $1500 that's it. That's the
basic game design and concept.. Atari gave you an idea/title that they want done and you wrote up what type of game should be made, etc.. (Home Alone, Bill & Ted, etc..)
I have never given an artist more than 25%... unless he is outstanding and
does a disproportionate amount of work maybe up to 40%. If the game concept is yours, the copyright is yours, most of the ideas are yours then if he insists on 50% then find someone else to do artwork.. There is no way he is going to get 50% from anybody.
I've paid artists on per picture basis and given them small points but it's
never gotten past 25%.. of course none of them have ever had any input on game design or concepts.
