BBS software was very regionalized. Being from a different part of Brazil Remote Access reigned supreme, while PC Board is something I saw once that one day when I dared dial long distance to some BBS in a different state.

The same goes for all the other software. In some areas LORD was _the_ BBS game, in others it was unknown. In my region BlueWave was the standard offline mail reader, in others only QWK or even weirder formats were the standard.
