I agree about the graffiti. (well , the rest as well , but i'd like to elaborate about the graffiti)
Honestly , as great and vibrant that graffiti makes the city, it tends to be extremely confusing for new people who don't know the history of the city.
For example : At the city gates , a guy named Yoshi sprayed his sic info and phone number all over the place to help and recruit new players. If in not mistaken , that phone number and alias hasn't been used since forever.
I remember as a newbie that I went to look for this guy and never found him.
Same with the Korova event that was sprayed all over the place.
Now some of this graffiti could be used beneficial in roleplay (Gangers paying to remove the Sinner suck graffiti from their turf and respraying their gang signs all over the place) , most of it is just old , busted down and decayed information that is only going to end up confusing people.
I honestly would love to see graffiti decay over time. This would also be beneficial for roleplay and would make graffiti mean something.
Gangers could pay people to keep their tags on the streets and people would actually pay attention to new graffiti that has been sprayed.
