If I recall correctly there is a bit of a wrinkle in the whole identity of Lavos at the end of Chrono Cross in that Lavos is described (perhaps figuratively) as a "cosmic seed". I think the idea of going to different planets and seeing how some of them have coped with Lavos would be awesome, but I think it would also be interesting to further explore that idea of Lavos as both a God-like figure, a masculine entity, and as a being that brings the planets it infects both greatness and inevitable destruction. After all, it was because of Lavos, intentionally or unintentionally, that humankind attained heightened intelligence (and, as such, civilization and technology) and discovered magic.
@SM: I'll probably check out Dragon Age at some point if I can get it for a reasonable price, which may be easier now that the sequel has been announced. Is it true that the console versions are significantly worse than the PC versions? I have a MacBook and a PS3, so I would have to get it for one of those.
By the way, if you're a fan of Yasuyuki Honne I would strongly recommend checking out the Baten Kaitos games for GameCube, if you haven't already. Honne was both the director and art director for those games, and the first one was also scripted by Kato. Regrettably they didn't have Mitsuda working on the soundtrack, but the composer the do have, Motoi Sakuraba, turns in what is quite possibly his career-best performance, with some truly fantastic tracks. They really feel like a bit of a throwback to the Chrono games, Cross in particular, and for the time being are probably as close to a true sequel as you're going to find.
Also, yes. Saito is badass. Aku Soku Zan, mofos.
