Because of the horrid downturn in the Mana games since the advent of "World of Mana" series . . . and the advent of the Crystal Chronicles series . . .
I've been wondering what could have happened to the Seiken Densetsu series had they continued with their original intent (Final Fantasy games done in an ARPG style) and their original title.
I think we would have had a much stronger series. As much as I love Secret of Mana and SD3, had they simply kept the "Final Fantasy Adventure" prefix and kept closer to the Final Fantasy series in content (if they were going to do summon's based magic, why not use FF summons like Titan instead of Gnome and Shiva instead of Undine, etc) I think the series would have had a clearer, more defined "world" and it would have been less likely to make such an unfortunate downward spiral.
Of course, it seems Squeenix realized just this when they created the first Final Fantasy Crystal Chronicles. Just like FFA, here was an ARPG that utilized established Final Fantasy weapons and items and spells and monsters.
Unfortunately, I can foresee a similar downward spiral for CC . . . it won't be too soon before they drop the FF from their name. And just like the Seiken Densetsu series, one or two games after dropping the FF from their name, they will probably devolve into terrible gibberish.
