It took me a few characters to finally realize the actual flow and how screwy it is.
I think for some wacked out reason Richland and Westview are put right close together - but the lvling flowchart is actually intended as:
Richland --> International --> Westview --> Downtown
Not:
Richland ---> Missions send player automaticaly to ---> Westview (regaurdless of lvl) ---> International ----> Downtown
You missions start sending you into Westview from Richland about level ... 13-14 or so >.o And it's 20 - 30 area where International is your 1 to 20 area. I believe this is more due to the fact that Richland and Westview are all one big piece, and so close together, and International (Chinatown) is more or less a completely separated construct, like Downtown. You can thank Monolith for this ... they set the play flow order order of the gang lvls all wrong in my opinion. How it SHOULD be is Richland and Westview should be more like Richland and International - switch the lvls of the Westview gangs with the Chinatown gangs (in theory). And then you should have a proper play flow.
Most new players don't even know they are supposed to go to International as their next step in their teen lvls, since it just starts pushing them into Westview by default. I know back in '06 when I started I spent so much frustrated time being sent to Westview - and didn't even know Chinatown existed.
But ... it's MxO ... for whatever reason it wasn't done the logical way. But, if you like the challange - of course it's always there and you are free to continue braving the wilds of Westview if you please.
Those are my just observations and my opinions on the subject.
