Level editing for NSMBW already?
This is awesome; I hope that it takes off in a big way, for two reasons:
1. Modding is brilliant; it's educational, adds replay value and can bring out the hidden potential in games (take the PC version of FF7, for example; it was a shitty port, but with mods it's far better than the PSX version)
2. It proves that some people modify their consoles for reasons other than playing pirated games. Whenever console modders try to defend their practice agaimst accusations that it exists only to facilitate piracy, they always bring up "backups" and "homebrew", but never modded games.
