PC is without a doubt the worst of the 3 cities. At least if you're into realism, which I am.
PC offers some different flavors, but for the most part, it's all just overly scaled gigantic theme park areas. PC feels more like Tony Hawk than ever. Every area you skate is the size of a 16 lane super highway.
It's funny cause I was always a little pissed about S1 and S2's lack of good banks, or banks that you can grind at the top of or banks with ledges built midway, and S3 has beaten that horse to death, reanimated it, then beat it to death about four more times.
The entire city is full of banks and banks with ledges on them. Every single area you skate has a bank now. It's almost stupid. I have yet to find a small, intimate spot like you could find on S2. I mean, remember the hidden loading dock spot from New San Van? There seems to be little to nothing like that.
Every spot you skate feels like a skate park or a skate plaza. Nothing feels like a city anymore.
Don't get me wrong, I still love the franchise and will play S3 as much as I played S2, and I'm sure Skate 4's city will be even more of a Tony Hawk Rollercoaster World than Skate 3, but I'm disappointed in the direction.
