Very ambitious work,
looks really nice. I can see the effort you put into that.

But you use some technically bad solutions.

Dont use WED Blocks for it, as you cant not use an effective LOD then.
Rather try to convert the buildings to models.
Or try around with map entities.
This way you can build your custom LOD.

The movement of the character and cars need a better collision handeling.
You should put much more effort into the character movement
procedures.
Dont use a second view for the map. (as far as I saw in the
video) This uses up extra FPS.


Nevertheless, it has a lot of athmosphere already!
I like the simulation of a populated city with traffic and passents.

(only the cars drive on the wrong side)

Legal: Right now you use a lot of brands (cars, shops etc)
So dont try to sell this without really checking for
the legal limitations. Else you can easily get in deep trouble.
