Absolutely the GS would crush it. Except that the C-64 had programmable character graphics, hardware scrolling registers, and sprites. These three things made it easier to do various games at 30 frames/second. So, visually yes, the IIgs' graphics were much better. But animation-wise, it was harder to do animation and scrolling at the same speed and with similar simplicity of code. [...] -- -- Jerry awanderin at gmail dot com
