Oh, Dalton, you are so hilariously awful.
This chapter is probably my favourite in the game. You get to see the downfall of a powerful civilization followed by a breakout mission on the Blackbird. You have to be somewhat sneaky and creative (or use Ayla to kill everything), and it's laid out pretty interestingly. The final Golem boss is a laugh, as is the last battle against King Dalton.
The best part, however, is the battle, or lack thereof, with Magus.
Magus wins the top spot for my favourite character of Chrono Trigger. It's really rare to find a neutral character who's handled so well. The poor kid really got kind of a crap deal in life and only wanted to destroy the evil being that possessed his mother and harm to his sister. His biggest problem is that he's a loner and not really a people person, so he tries to do everything on his own. Even in the war against humans in the Middle Ages, he mostly just tagged along with what the Mystics wanted (though goading them a bit, of course) so he could to train and get more power to become strong enough to defeat Lavos. Magus is incredibly self-serving and chaotic, but not evil, and you really get to see all aspects of him throughout the game.
The first time I played this game, I totally recruited him completely on accident. I wasn't properly healed and ready for a boss battle, so when he asked if I wanted to fight, I said "no" in hopes that it would give me time to head back and heal up. >_> Then I recruited him, woohoo! \o/ I've since recruited him in every playthrough I've done, and I always name him Janus.
If you choose to fight him and you have Frog on your team, Frog will insist on fighting him all by himself. Maybe someday I'll do that.... but it would be really hard to play through and not recruit my favourite character.
PS: I love having Magus in my team and then going back to the Commons or whatever so Janus's little purple cat Alfador will follow him around. <3
