Weapon curiosity

The question is, who hasn't beat them? I remember my first playthrough: Since I neither wanted to do Chocobo breeding (For Mime and KotR materia.) nor Death Penalty leveling, I did Emerald first with Yuffie's Conformer combined with Doom of the Living and had Cloud Omnislash all the time, easy. Traded the Earth Harp for the Master Summon and beat Ruby with KotR spam, also easy.
I think the Weapons from VIII were more entertaining.

Yeah, no joke. It's really only setting up for the battle that's even remotely difficult. Fighting both Weapons is exceptionally tedious with a repeat-ad-nauseum strategy. In FF8, I tried to beat Omega normally, but I decided it wasn't worth it and just "The End"ed it. Taking out the Weapons in FF10 though was quite easy. I had much more trouble perfecting Tidus' ultimate weapon.

I actually didn't beat either one, because I got tired of doing all the shit to get ready. I could have kept working on it and beaten them, but shit, when you've already spent one hundred hours playing the game, everything gets really old, especially kicking the asses of weak enemies for hours to power up your materia.

Ozma (IX) was just plain annoying. You couldn't really do anything about it, he either kills himself or he blows away your whole team in one turn. On my first try, I was prepared to the max just to have him one-shot my whole team for inevitable maximum damage with Meteor. Another try he used Meteor on his first turn and barely harmed my guys at all. To defeat him all you needed was for him to use his shadow-based screen damage spell thing which healed your team due to shadow absorb gear and Vivi or Amarant to counterspell said attack. It took me like ten tries before he finally shove Meteor up his ass and I was able to beat him. Just lame. My most favourite Weapon(-like) fight of the FF series was by far Yiazmat (XII). I encountered him prepared to the absolute maximum and I still had to struggle and make sudden changes in my strategy because he kicked so much ass in his final phase.

And well, I couldn't play a game without beating all the optional bosses. It's pretty much my only goal from the beginning - the whole time through the game I'm just planning the best course for my characters to be at high potential when the time for the optional bosses comes - the story-dependent bosses are pretty boring, for example after I beat Yiazmat and went to the final boss I struck him down with two turns from Fran with her Wyrmhero blade, good game.

Funny story - the first time I fought Ozma, I beat him without breaking a sweat. I was amazed and a little disappointed. My friends were jealous and wanted to know how I did it. I didn't really have anything to tell them. It was just luck that Ozma did shitty a job the first time I tried to fight him.
