nothing...Retro didnt exist. They were founded by Jeff Spangleburg(an ex acclaim exec) with some money from nintendo. Anyways when they started they were making four games all for Dolphin(Ravenblade, Metroid(or something similar), a twisted metal clone, and a footbal game). Nintendo finaly gave them the metroid license and they worked away. A prototype version of Metroid was shown and most hated it. Anyways they were botching up and Nintendo did not like it. Half the employees of the company were fired. Including Mr. Spangleberg. Soon after Nintendo sent in some corperate guys to clean house reggie style. A year later Metroid was released and got solid reviews across the board.
