if you go platinum there's no way you can be considered a regional classic record because if you have a million plus fans obviously there's niggas in other parts of the country fuckin wit it simple as that..you dont sell a million units in one region
a regional classic to me is 8ball and mjg - on top of the world..a personal classic to me and others who probley grew up off that old school sauve house and mid 90's south music but it didnt even go gold and them dudes wasn't out there on yo mtv or the radio like that cause they didnt break out nationally like outkast and no limit..same goes for c-bo till my casket drops and twista adrenaline rush
but i agree with it his standards for a classic and i agree with some of the others reasonable doubt isn't a classic the blueprint would be his classic based on the standards old dude had
