Maybe Nintendo is just evening out Koopa Troopas with Goombas. In Mario64, Goombas were EVERYWHERE and there were 3, THREE, Koopa Troopas in the whole game. And in Mario Party, the Koopa was a good guy. Maybe Nintendo is just trying to get Koopa Troopa back to its normal self and is not going to have any Goombas to emphasize how tough the Koopas are. Either that or your friend`s a liar.....
