As most of you know, every character in the game is paired up with another as rivals. The only pair we know for a fact is Heihachi and Toro. What other characters do you think are going to be paired up as rivals? One rivalry I think would be funny is Nathan Drake and Big Daddy, and Nate could call him a mutant like he called those giant dudes with the machine guns in UC2 XD
Drake and Big Daddy is a nice idea. You can imagine how Drake is going to Rapture to find treasures..
Kratos and Parappa would be funny.
Jak & Daxter and Ratchet & Clank SHOULD be rivals.
Sackboy and Crash, like the old mascot against the current.. if Crash is in.
And maybe Sly and Radec? Sly wants to steal something from him.. like his suit or guns..
I like all of those ideas, especially the one with Sackboy and Crash. There was a post on the forum asking who the face of Sony is, and I would say it was either Sackboy or Crash. Them being rivals makes perfect sense.
