What game series should come out only once every videogame generation?

Good additions everyone.

I played the Tomb Raider Legend for 360 and it felt a lot like a ps2 game (then I found out it is a last gen game ported over). Then they did the remake which again was done on all platforms imaginable. We will see how Underworld does I guess...
