Pretty much, Uncharted has Golden Abyss, Dragon Quest has 10, Final Fantasy has 13 and others, Zelda has CDi Games, Pokemon has too much water, Etc Etc. Mario Kart has the GBA, Civilization has Civ V (without DLC). I can break down any game and I can find the black sheep. 

 

What would be Serious Sam's black sheep?

Serious Sam 3, or that PS2 game?
