Damn, I had been expecting this to be 30fps untill now, and I had though it looked pretty good even then. The distant buildings did look flat and all, but now that this turned out to be 60fps, all is completely forgiven to me. I think all is great lookwise.
As for city aesthetics, I too thought the original looked cooler. There was a clash of how clean and sterile architecture looked from inside buildings and street level, to how slightly grittier and messy things were on the rooftops (though still quite clean) from what I saw of the beta footage, the rooftops look almost as tighty as interiors. I, don't know, it gives a certain sense that those rooftops were deliberatly made for someone to traverese through, which of course they were, by game designers, but the illusion that the player is improvising through some unintended alternate route is not as strong.
