NES Tennis in 3D was too tricky.
Nintendo has admitted there are problems remaking old games in stereoscopic 3D.
Designers got stuck adding the extra dimension when they found out that it altered gameplay. Nintendo’s Takao Nakano, leader of the 3D Classics remakes, told Satoru Iwata that large portions of game code had to be completely re-written.
“In the original version, the game unfolds on a flat surface,” Nakano explained, talking of upcoming re-release Xevious. But in the new version, the player’s ship Solvalou is seen to be floating in mid-air.
