Sephiroth because:
A) I haven’t played the one with Kefka.
B) I spat peas when someone sang the crazy choral Sephiroth theme:
I LIKE HAM AND CHEESE HAM AND CHEESE HAM AND CHEESE I LIKE HAM AND CHEESE HAM AND CHEESE HAM AND CHEESE…
PIZZAROTH!!!
do do do do do
PIZZAROTH!!!
You absolutely MUST play FF3a/FF6j. It’s been ported to the PS, with some really great new FMVs. Fantastic gameplay, though I don’t like some of the characters. And you get to have FOUR people in your party at a time.
As for Sephiroth vs. Kefka…Kefka’s a better villian, true, but I hate the clown bit. Sephiroth is cooler, and better looking. They both have their good and bad points (as villians).
Just came out on GBA/DS last month too. Best of the series IMO.
