I prefer cartridges. A disc gets scratched to unreadability within a few months in my house, but I've got all my old Game Boy cartridges, reaching all the way back to 1996, in perfect working condition. Discs take forever to load (even on the fucking 360!), and you have to buy memory cards, hard drives, whatever for saving. The higher capacity of a disc means nothing to me, because I play games for gameplay too, not just for cinematic cutscenes. If I just want cinematic cutscenes, I'll watch a damn movie. I benefit more from fast loading than from having three hours of movie footage on my game. Discs are popular for high capacity storage (much of which is often devoted to bonus footage or other useless extras) and for low cost, but for all that low cost I don't see lower game prices.
