Yes, it's a comman, and to me a MAJOR, complaint of CC. I think only two characters get a decent amount of character development and even then, I'm stretching it with Harle...Kid is the other one...Serge has a background, but, of course, no real character development (like I've said many times before, at least Crono had a fuggin surprised sprite), but he's the silent protagonist, yeah?
Character Development just sorta fell to the wayside. Instead, they focused more on a great storyline and even though I hate the sacrifice that was made, I'm still proud and glad to have CC as part of the Chrono series.
HUZZAH~!
