Your list is quite good, i havent buyed any new generation system, iam still with ps2 and psp, i am waitin to FFXIII to buy a PS3, so maybe i am missing most impressive boss fights., my list is based in my actual feelings fighting that battles, the feeling of wowness, that means that fights that have a heavy story background has preferences in this list.
10. anubis(zone of the enders 2): awesome effects, graphics, music and zero shifts makes this fight impresive
9. That elite squadron that you face in ace combat x, had the best music, very good dialogue, and it was the best dodfighting i have ever had in the series. quite impresive
8. Darkcrussader (Vagrant story): figthing alongside sidney in a 2vs2 fight + my favorite boss fight theme of the game.
7. Magus, Tyranno and Queen zeal(chrono trigger): were my first epics boss battles
6. Guilderstern (Vagrant story): "come riskbreaker help me to celebrate my Ascencion", fighting in the summit of the great catedral with a emerging god, great.
5. Atma weapon VI: was my first epic and difficult fight in an rpg (at the time i played ffvi the only rpg i have played was crono trigger)
4. The Boss(MGS3): my favorite fictional Femenine character of all times, this includes all the media(movies,anime,series,books etc.), a bed of white roses, the snake eater theme, the feeling that she is far superior than you, and the emotional signifiacne.
3. Kefka all tiers(FFVI): the emotional moment, this fights represent for me the godness of kefka, you begin fighting in his hell and then you advance until you reach the glory of kefka, with his angel form, with that insane and at the same time divine light in the background, epic. the music dancing mad is epic too
2. All the Shagohod boss sequense (MGS3): at this time this is the most awesome boss fight i have ever played, cinematic, shooting to the soldiers, pursuit, sniper shots, a kiss from your girl, the music, just EPIC.
1. Sephiroth(FF7) - the culmination of my favorite FF and villian, when the voices in "one winged angel" starts to sing i was just blown away (was the first fight with a epic song with actual voices that i have experienced), and when he uses superonova i just began to shout out: God please help me!
sorry for my superbad english
