Why did the N64 DD, SEGA CD, neo geo disk addon (there is one right?) and all others fail untill the ps1? I know as a kid I didn't like loading, and in my ignorance would cry out why does my ps1 have them but not my n64, but I was always careful with the disks so no problems there. Were people scared or something, did cds seem like a bad medium for games? What was the deal?
