"When we built Amiga titles for the first time, we were coming out of the 8-bit world; we were building some IBM PC stuff, but for the most part it wasn't high quality, relatively high resolution high color stuff. And so the Amiga, for us, taught us a whole bunch of new things. We had to get good at music, we had to get much better at art, we had to get better animation that wasn't all sprite animation, we had to do 3D for the first time -- a whole bunch of things that we had to do."
Unfortunately, says Hilleman, "None of that paid off except Deluxe Paint, really, in the Amiga world."
