Postal 4 is shit, but not truly the franchise killer.
What I think Postal 4 needs in order to have a tiny bit of soul is mod compatibility and that stupid co-op mode.
Early Access and increasing the price are what ruined Postal 4 for me in the first place.
RWS thinks that just fixing bugs and all that shit in Postal 4 can be saved for some other time because Postal 2 was buggy before and they screwed it more up.
I wish RWS tried to ressurect Flesh and Wire or any project they had in their mind before creating Postal 2.
