Hmmm, tough choice... one thing, this might contain some slight spoilers (as does this whole topic x_x ).
*** VAGRANT STORY SPOILERS ***
In Vagrant Story, the battle with Sydney against that one guy who summons a dark armor (I can't recall the guy's name though). It was in the Snowfly Forest (again, not sure about the name...). That battle was really sweet, especially once Sydney turned out to be on my side, after casting Prostasia on me. ~_~

*** KINGDOM HEARTS SPOILERS ***
Having beaten Sephiroth on expert mode! I finally succeeded in doing that earlier today, and damn, what a rush. The battle was really sweet, even though I died lots. ~_~
Also, I love the ending. *sniffs* Well, I love all of KH, but the ending is really pretty. Simple and Clean (or the Japanese Hikari) is a wonderful track, and the movie looks beautiful. (I <3 Kairi. XD )
One other thing, the -Final Mix- secret movie, Deep Dive owns so much. I can't wait for KH2, and I really hope it'll be something like Deep Dive. ~_~

*** FINAL FANTASY IX SPOILERS ***
Trance Kuja! He looks very pretty~! And I loved the whole Terra part, the dialogues and all, especially Garland's whole Angel of Death talk.

*** XENOGEARS SPOILERS ***
"Blossom, o fallen seed, and draw upon thy hidden powers!!"
Just to quote a line from Grahf's vocabulary. ~_~ Seeing him in battle always means loads of... fun. XD And the whole Id/Fei thing is very cool as well. But the whole Xenogears story owns. ~_~
And which is even better, I'm getting the Xenogears Perfect Works ~the real thing~, 300 pages of Xenogears art goodness! Woohoo!
*** END XENOGEARS SPOILERS ***
Well, that's all I can think of at the moment. There's probably more, but maybe I'll post that some other time. ~_~
