I agree about Tita. I normally roll my eyes or mash through dialogue from kid characters in games (like Ys Seven Elk)
Awww... I really like Elk, too! He's my avatar on the Ancient Land of Ys forums, in fact.
I tend to like kids in games overall, though, because I like "kid adventures" -- grew up idolizing the Goonies and reading The Three Investigators and Encyclopedia Brown, so I guess that comes with the territory.
I only like them when they're written well, though -- and Falcom's pretty good at writing kids well. The only real exception to that I can think of is Terra, who is far and away my least favorite "Ys girl" of all time, ESPECIALLY in Ys V. Man, Ys V Terra sucks so bad.
