So after looking over what we know it became a bit clear to me the way the story mode will unfold and why.
The rivals are setup by polygon man.. he basically is a jealous evil jerk who knows to get them when they are at their weakest. He sets them up to battle.. and once one of the rivals is defeated he will jump in and try to take the remaining life out of the fallen rival. You will then have to save your rival.. and yourself.
Imagine evil cole saving fat princess or the other way around?
I hope for this.. wouldnt it be cool if by consuming your rival he also uses their worldly powers against you? Which brings up why there are many easter eggs and references. All that "content"
During the consumption of your rival they begin to turn into just polygons.. and polygon man becomes more and more detailed.
The Ending? You become friends with your rival.. :-D
Agree with mtjjrstcw1 sure id be cool to see lets jak and ratchet beat the hell outa eachother only to save one another but it just wouldnt make sense and sweet tooth saving somebody yah like thats going to happen haha.
I believe the premise of this game is that this is all just an internal struggle digitally happening inside your PS3 (similar to Wreck it Ralph in the sense that it was all based in an arcade world) and somehow Polygon Man has taken over (or maybe has always ruled) the PlayStation Universe. The question is ..... Is Polygon Man forcing everyone to fight for whatever reason (like a tournament), or offering a prize to the individual who does blah blah blah first (like first one to reach a destination), or holding something precious from all the individuals (like a way to return home, or fat princess cake).
Sweet Tooth doesnt care if he dies...he just gets **bleep** when someone not worthy TRIES to kill him...If his life depended on it, well boys and girls...he wouldn't care, it would just give him more fuel to kill
