I'm still not over it. Did piracy kill them?

Yeah, that was the weirdest shit.
Actually no, the weirdest shit was one of the late-game bosses dropping a diaper he was wearing that you can equip.
Why.

Mario and Luigi!
Mario and Luigi PLUS BABIES!
Mario and Luigi PLUS BOWSER!
Mario and Luigi, but Luigi Fell Asleep!
Mario and Luigi, and another Mario!

What's the difference between Pirating those last 4 games and replaying your copy of the first Mario and Luigi games 4 times over?
