1: The programmer's ending? Hell yeah, meeting all the programmers and stuff, learning about the 9999 hit combo, and just having the developers make fun of you is great. Plus, taking on Lavos as Crono alone is just awesome.
2: The Frog ending: When everyone in your world turns into a frog, what do you do? That's what I thought.
3: The Repetite Ending: Same thing. Same. Thing.
4: Frog Vs. Magus: Godly. You don't even see the fight but you know it's good. The best part is that technically, you don't even know who wins the battle (my wager's on Frog: as the credits roll the last thing you hear is the Masamune slashing).
5: Lavos Ending: Yeah, the world can end. Boo Hoo, try again. Loser.
6: Magus Vs. Lavos: Hey, we all knew it was possible. He doesn't lose his powers, and hopefully he kicks some REAL arse.
7: The Nu ending: No clue.
8: The Regular Ending: I guess that's pretty cool, with the whole rise above the clouds thing...
9: The Black Omen ending: The cool part about this is that your past and future is altered by whether or not you killed Magus. I like seeing Frog turn back into a human, and it's worth it to see Crono not be in the party and to check out what happens.
Then there's the variations on the real ending: Whether or not Crono's alive, whether or not everyone tumbles out of the telepod, whether or not Lucca comments that human Frog actually is kinda cute, whether or not the telepod is used to save Crono, whether or not Marle comes with them.... I'm not entirely sure which ending is the real one, myself... But there's definitely a lot of variations.

Spoiler:
When Tidus jumps off the ship to meet his father, as Yuna tells him she loves him...that's touching stuff right there...

Spoiler:
Bowie, main character, and everyone finishes up Zeon, the princess who was kidnapped by Zeon kinda early in the game is under some curse so she won't wake up. Bowie kisses her and she wakes up, they fall in love, tradition legend/hero type ending.

Spoiler:
Basically Zidane goes back to rescue Kuja (His 'brother'... evil) from the depths of the Iifa tree. It turns out that they both get stuck there while the rest of your party escapes for the better. Afterwards it goes into the traditional "What are your party members doing afterwards" cutscenes. At the very end, another play is being put on for Garnet, now queen of Alexandria. The play goes on as normal, and at the very end, who pops up on stage, other than Zidane! Garnet rushes down, loses her amulet, but goes on anyways.

Spoiler:
In the japanese ending to Megaman 7, Megaman doesn't say "I am more than just a robot!" He just stands silently, knowing there's nothing he can do to stop that rule. It's a simple mistake that the american translators put in that's caused so many disputes in message boards relating to the megaman/megaman X connection story across the internet. God damn you, Capcom of America. God damn you.

Spoiler:
After Wily's last ship explodes, he falls to his hands and knees and says, "Alright Mega Man, you win. Sorry for all the trouble. I'll go quietly." At this point, Mega Man charges up his mega buster and says, "I don't trust you Wily! I gonna do what I should have done years ago!" Wily backs up saying, "You forget, Mega Man! Robots can't harm humans!" Mega Man quits charging and says, "I am more than a robot! Die, Wily!" At this point, an alarm goes off and part of the ceiling falls, pinning Wily to the floor. A small piece then bonks Wily on the head. Treble comes down, barks, and teleports Wily out. At this point, Bass appears and says, "Too late, Mega Man! He who hesitates is lost! We shall return!" Then he also leaves and the alarm sounds again. The credits will roll, during the credits we see each boss robot Mega Man faced in the game, along with its designer and number. The last 2 to be displayed are Bass and Treble. At the end of the credits, the view goes to the sky where a shooting star can be seen, then back down to Big Eddy's. Mega Man goes inside and a photo is taken. Beat flies, Rush yawns, and Auto (with his hyperbolt in) puts up his fan for the photo, which has a red dot like the Japanese flag.
