Just some quick questions and concerns. I downloaded Wing Commander Arcade Demo and Battlestar Galactica Demo. They are not real 3D games? Seems like just updated Asteriod games. Lots of fun though. I'm thinking of actually unlocking them. More Questions: 1. How do they fit these games so compactly? The demos are only about 40Megs. Are the unlocked versions larger? I guess they are only $10 each, so not worth putting them on disc. 2. How do you back these up? To a memory card? Can you re-download them for free? Can you transfer them to a different XBox? What if I get a replacement XBox in the future? 3. I'm a videogame collector. It's sort of strange not getting something to "hold". I was just at Best Buy and bought the PC version of Battlestar Galactica. Yes, it costs twice as much ($20) and I have to try to make it work on a PC, but at least I can hold it and have it be a part of my videogame collection... What do people plan on doing when you want to keep these games indefinitely and play them well in the future when the XB360 becomes a "classic system"?
