I was exaggerating, sorry :) I don't know what that is in today's money and am too lazy to find out, but it's a lot. I don't know exactly the difference between regular home console carts like those for Megadrive and SNES, and those for the Neo-Geo, but I think the main difference was that the Neo-Geo was essentially an arcade system, so didn't sacrifice anything for the home cartridge version. I think the price was mainly so much higher due to the comparatively huge ROM chips back when memory was rather expensive. Typical SNES games were 8 megabits I think, and the largest (according to Wikipedia) was 48. Neo Geo could go much higher and games were often 100 megabits or more.
