I think that's it. The city itself looks OK but the weirdness comes from the ambience, there being only like 2 unique NPCs, reskinned and all wearing the same 1940s style attire; also the fact that there's no cars except taxis, making very scripted turns. I guess they needed to showcase that part of the game since it's…
I mean, the "real" city looked quite jarring but I think they showcased it because it was relatively well polished. The dark forest area on the other hand looked really bad to me, maybe I'm spoiled with seeing more cutting edge stuff being used the last few years but damn it's ugly. The cartoony desert town was fine for me…
