Save scumming is when you save right before leveling up and keep reloading untill you get the stat increases you want.
That too, yes, but I've also heard it used in the sense of backing up your saves just before trying something risky, such as a boss fight or teleporting to an unknown location.
I would call backing up saves for cheating. It's just a way of circumventing the one slot restriction, which probably was there due to technical reasons.
Technical limitations, perhaps, but also because Wizardry
and other CRPGs from this era were so closely tied with tabletop (D&D
-style) gaming -- and in those games, at least at the time, you didn't necessarily get "do-overs" if your character was wiped out, unless you had a very
generous and/or creative DM. The single-save aspect may have been a conscious attempt to replicate that atmosphere in a computer game, but as computers evolved and gaming habits changed, so too did this philosophy.
I agree, personally I
don't think it's cheating either... but the sentiment is
still out there regardless.
