I dunno why some people seem to mistake 'discussing' for 'arguing'....nobody's "Pistols-At-Dawn"-ing the individuals on the other side of the fence, and it also seems like we all understand that S.E. 'adjusted' her name to Aerith after the original release, and that's what it's going to be now. As I understand it, we're just discussing our preferences, who likes which name better, and why....yknow, since this is a forum? If the thread went, "Hey, remember how Aerith used to be Aeris and then they re-translated it?" "Yes. Now shut up about it, and never mention that again, cos it's settled", that wouldn't be much of a thread at all, now would it?
Also, as far as name symbolism goes, is it really coincidental that Terra's name is 'earth'?
