Edit: In the build I played the track can not in anyway be seen as gorgeous, the lighting is great in the game but the backgrounds in this track aren't good at all.
Ah, you're talking about modeling of buildings and not graphics.
But watching the direct feed video, I find PoDi has very well modeled them. After buildings are ugly ? Yes, as in real life, just see the photos posted by Samus. In any case, review on this track is different from Spanish media, which they have enjoyed a lot.
I look forward to be at Gamescom to make my own opinion !
