The initial loading times are pretty obscene, and in the multiplayer, you sometimes get kicked out of matches for no good reason. This wouldn't be too bad, except that there's a whole metagame about collecting supplies in each match to feed your growing clan of survivors, and when you get kicked, it counts as a loss and a bunch of them get sick or die. I guess another con is that it's incredibly depressing. Just about every plot event is a huuuuge bummer, and the worst part about it is how damn plausible it all is. The decisions people make suck, and yet their motivations are clear and you KNOW they made the choice that you would have in their shoes. I've heard of a lot of people who can only play it in short bursts, because goddamn. For example,
Yeah, the ladder thing is definitely one of the differences. I picked up Uncharted 3 when I got it since it's pretty cheap by now, and the difference in the height of things Drake can climb vs. what Joel can climb is pretty damn staggering. You can still climb up to whatever you can reach, but you never even really jump unless you're hopping over a short gap.
Again, I would hardly call this a zombie game. The outbreak at the time the game picks up was 20 years ago, and while the infected still prowl around, regular-ass people are what cause the biggest problems.There's people at point A and people at point B, and while there are zombies in between, it's the scavengers and raiders that'll get you.
