I think I did well considering this was my first attempt on FFV to best them and I did it without having to farm dragon lances, which I really can't be bothered to do (despite loving dragoons). Omega was a pain due to his "circle" attack, but he kept on missing on my fourth try. Shinryuu was... nothing.

As for "challenges", you have to admire people who take them on, but I count whatever the producers have thrown in the game as fair play. Besides "Slots" and "The End" (though it is funny to watch such things happen!)
