I like the idea of an all digital gaming future. A disc is a physical medium for storing a digital idea. It's vulnerable - light, heat, and physical forces can all damage the contents. It's a restrictive medium too, and we had to use it in the past. It was the only good way of distributing and storing these digital goods, but we now have a better way: high-speed internet and high capacity hard disk drives. The disc has served us well, but old technology has to be retired one day.
