You played over Against the Black Knight?
For shame. For shame.
As cool as the song is, it didn't really fit the "epic duel" theme to me. I think it would have helped better if they used THAT for the map theme for that fight, then use a more upbeat/intense version (maybe do something like Rare does where they change the instruments based on the events that're going on) when the actual fight starts. The final map theme I feel is inferior to the previous one, and the Black Knight's battle theme felt like it was more at home in a cutscene than a fight scene. I just wanted to treat myself for finally finishing a Fire Emblem game legitimately (I finished Sacred Stones in the past, but it was on an emulator with lots of savestate and arena abuse :V). Besides, the battle was painfully short as it was, barring the BK's prebattle dialogue, so the part where the song would take the most effect is kind of short-lived to me.
On a related note, I started FE10 today. I'm annoyed I couldn't finish chapter 1 in less than 8 turns. Curse me and A- my need to to keep Edward from getting hit with a a Hand Axe to the face, B- going after the boss kill AND the Hand-Axer kill, and C- my sudden compulsive need to finish each chapter in the time limit to get the max bonus EXP; it kicked in about halfway through FE9, and continued as I realized how close some units where to 20/20. I ended up BEXPing Ike, Jill, Marcia and Zihark to Max, fed Astrid a few kills before BEXPing her (she was high enough as it was), then fed Oscar my leftovers and let him kill things in the final battle.
Anyways, gonna redo that chapter and just ignore handaxer dude next time. If anything, FE10 teaches you to optimize your strategy and know when to either run like hell or take your time, even if it is a bit cruel about it. This definitely feels like a game that should be played right after FE9, and I think I'll enjoy it (for the most part).
EDIT: How did this post get so long ahhhhh D:
