And finally, in Capcom Classics Collection: Remixed (PSP), there is a secret game sharing feature. We didn't have time to go through the official paperwork and testing needed in order to claim the game supports game sharing, but we put the feature in anyway, probably in a better form than how you're supposed to do it. Here's how it works:
Launch any game from the main menu of CCC: Remixed. Take out the game disc. The game you launched should keep playing with no known problems. Give the game disc to your friend. Your friend can now play any game he wants, but have him launch the same game you did. Now you can "join game" and play a wireless multiplayer game with your friend, using a total of only one disc. Interesting to note that this implementation of game sharing required no interface screens at all: it "just works."
Speaking of holiday gifts, you could still order my Playing to Win book in time for the holidays, either for yourself or your gaming friends.
