I may even pick up Seiken Densetsu II one day, just to see the dialogue that got cut out and the changes were made; being a big fan of the series makes me interested in those sorts of things, and I'm sure there are others interested in it as well. Plus, in that case, I'm pretty sure Woosley said something about Secret of Mana being hard because he had to cut out a LARGE portion of the dialogue for space reasons. ^_~
Even then, unfortunately, we'll never see what Seiken Densetsu II was originally designed to be. I could JUST imagine being a translator/localization guy on a project like that.
Square Japan: "Hey, buddy, we've got a new project for you."
Translator: "All right, what is it?"
Square Japan: "Well, uhm... it's a SNES game. An RPG we originally wanted on that SNESCD thing... But we had to cut out 30 percent of it's content to make it fit on a cartridge instead of a CD. And the dialogue code isn't in any coherent order. Oh yes, and by the way, you'll need to cut MORE out of it when you're done. But make sure that it's epic or you're fired. Oh, and you've got three weeks to do it in. Have fun!"
