I might be in the minority, but I think silent main characters is a must for the Chrono series. It's an RPG tradition that's been dying out, but I think it's a staple of the Chrono series that could be kept. Sure it's a bit wacky, but it's also one of the series' charms. It's also great to see how creative they can get with the sprites. Chrono never talked, but you always knew what he was saying.
