People playing dense like this isnt the scummiest shit ever is confusing to me, is it because its Nintendo? Look man I love Nintendo but this aint cool.
And there it is. The classic.
And no, it's not because it's Nintendo that I don't think there's a problem.
Hell, if MikeProtagonist is right, Mario's call for Luigi doesn't even happen commonly. You'd think it would happen more often if it was meant as a marketing tactic.
If Mario was saying stuff like: "Where's my brother Luigi? Do you know where my brother Luigi is? Can you help me find my brother Luigi?" and he kept saying it constantly, then yeah, I'm probably think there's a problem.
