no, you don't really.
But they're close to the same quality Imo (I'm not that big a fan of them). And they're short. So I'd play the first one anyways unless you really can't find it. To get the most out of 2.
You could probably order Uncharted 1 internet... but if you really can't get 2. Then it's not a big deal.
