Turns out that once you beat Mario & Luigi Dream Team (Bros.) on Normal mode, you are given the option of starting again of Hard mode, where damage taken from enemies is heavily increased, you aren't given the option of starting the battle again when you get a Game Over, and you're only allowed to carry a maximum of 10 items at a time. And let me tell you, it's just nasty.

Not that gamers haven't already built up those particular muscles...
