As we all know, we can't backup our VC games, at least not in the sense that it will work on a replacement console. Sure if the Wii breaks and you get a replacement, you can call Nintendo to transfer the license. But has anyone ever considered what will happen in the distant future, when games get pull off the shop channel that have been on there for too long (let's say 10 years from now), and your system dies, not just one or two of your downloaded VC games, but ALL of them will be lost forever if Nintendo discontinues the download service. It's terrible that game companies are so fixed on making money and preventing piracy that they don't take these little things into consideration. It's pretty messed up to not let the people who give them money to even backup their games.
