Mario's Mansion

Mario's Mansion is a game about Mario killing Luigi then Luigi's haunted mansion he was buried in becomes even more haunted! But Mario didn't care until he found out that Luigi was actually rebuilding his own body to live again so Mario goes into the Mansion to summon Luigi's ghost to the UNDERWORLD! It is very gory and death-like.

And Rated E.

Gameplay
You must control Mario and use the Poultergeist SUPERN00BEDITIONDIE and kill bosses. Luigi is the enemy. When you suck up ghosts, they are shredded and their blood is splattered everywhere! (and the game is still Rated E). Bosses are fought without the Poultergeist SUPERN00BEDITIONDIE because the bosses are allergic to the Poultergeist SUPERN00BEDITIONDIE and Mario hates allergies too so he understands and destroys his Poultergeist SUPERN00BEDITIONDIE. You do not fight Luigi at all, because at the end Luigi kills himself.

After you complete the game, you can play as Birdo who instead of using the Poultergeist SUPERN00BEDITIONDIE, uses the EIDNOITIDEB00NREPUS tsiegretluoP. If Birdo dies in the game then the entire game resets itself and you have to replay it as Daisy. (P.S. Daisy is cheating on Luigi in this game, because Peach was cheating on Mario with Luigi)
