So listen, this is what I've noticed a while back.

Does any of you remember Crash Bandicoot for the PSone? :o
(You're supposed to say yes)

And do you remember how successful it was? :o
(You're supposed to say yes)

Well think about its games; It's first four games to be precise.
It had Crash Bandicoot, Crash Bandicoot 2, and Crash Bandicoot 3: Warped,
Well what comes after that? A Kart Racing game for the franchise.
And why is this the winning formula?
Because Naughty Dog has brilliantly copied the formula of the greatest franchise ever:
Mario.

Mario had 3 "Mario Worlds" before it developped the infamous Mario Kart.
So did Crash Bandicoot. Maybe this is why it's so successful.
But it didn't end there.

After Naughty Dog ditched the series,
they moved on to the PS2 where they executed the same plan.
That same plan was called: Jak and Daxter.
There were three Jak games before they made Jak X: Combat Racing.
Jak and Daxter became one of the best series for the PS2.
A coincidence? I think NOT!

So the question is, or the point is;
I'm going to make a bet. Although stupid,

I bet you that Uncharted is going to have a racing game. (I'm joking. -__-)
