So one thing I love in videogames is to "live" on them while I play, which means that when I feel down or just want to have some fun I go out ingame, playing with traffic, talking to people...

In Chicago (WD1) I felt I lived in a grim world and it went really well with the situation I was living IRL. I didn't play it on release, but more when I felt like I fitted there. It was a living world, people walking, talking, making their own lives... It was dark, but it was "real".

In San Francisco the tone was lighter, everybody was happy, there was light, there was sun and of course, people were even more alive there (thanks to new technology you could animate the world even more). I loved to go there for having some fun and felt like I was part of that world. The sunny San Francisco was my home from the day it came out until the day I get bored of it.

Now London. London seems even more dark than WD1, which I don't mind (I may even like it) but it seems from what I've seen in the trailers that its dark for the sake of being dark. The thing that they most showed in trailers was violence. Gunplay and takedowns. Nothing about the living world. It seems you'll be there to make quests and fight some NPC, you won't be there to just walk around the city. They said there will be daytime but for what they've show it seems that daytime will have the same dark feeling as night. Of course this is speculation, but it looks like it will be too grim to make you feel at home like WD1 and WD2 (mostly WD2) did. I hope I'm wrong because I'm going to preorder anyways and give it a chance, they didn't disappoint in the other two instances of WD
