Super Mario 3DS has that gay giant coin thing like the normal DS version too, except instead of using big coins to unlock paths and mushroom houses they make you GATHER THEM SO YOU CAN OPEN THE DUNGEON AT THE END OF THE WORLD.
that was really gay, i had only 20 star coins and i got to the castle and it asked for 50.
i quit playing for some time after that
I enjoyed the Mario Kart 3DS really, even though its just the DS version with HD and new maps
