Most Gangsta Rap started out as "Reality rap" and Story telling but like I said before dudes got that paper and sold the hell out worse than Hammer ever did. PE had fell off by 93/94 and the only one who stayed solid at a national level was Cube and then he eventually decided to do the Movie thing more, and from what I remember of his stuff in the mid to late 90s he fully embraced the negative elements of Gangsta rap.
by 95/96 Rap music in general started to go down that path of glorifying the worst things about black society vs telling the stories of these things and putting context on why it happens (like Gangsta Rap initially started off as).
NWA had skits about kid napping chicks and putting them in the trunk and crap
