==Old? Female?==

Some suspension of disbelief is necessary to accept the Barbarian character as presented in Diablo 3. After all, the barbarian was male in Diablo II, and the story in D3 is identical for the male or female versions of each character, thus you can play a female Barbarian in D3 whose past history includes all the events in Diablo II. It's also an interesting concept to have the same character return in D3, as a grizzled veteran of countless conflicts, as a grown man (or woman) who defeated the three Prime Evils twenty years ago... and who starts off D3 at level 1, without the ability to do much more than swing an axe.
