I'm your opinion :)

It would be very nice, if more different faces for the own charakter would come out.

At the moment it's hard to move fast between the citys. I would find it good, if there will exist bikes or something like that, in the next update. Also interesting would be the possibility to spawn directly by friends (their position) over steam, to play immediately with friends.

I think you're right. A teleporter would be bad, because we could jump directly to the friends and the loots, if somebody is standing over there. This would mean, that you faster collect your loot and lose the fun, to find the loot. But some bycicles or montainbikes would be very nice. In the reality we also can't teleport and the near realism is that, what raise the funfactor. (Thanks for your very fast answer)

If a person get ill or hurt the screencolors change into black and white. That's a nice idea, but there also must be a possibility to get back the own maximum healthy, with colorful fun.
