The poll shows that the top three are: Canderous, T3-M4 & Zaalbar. Interesting situation... if I read this correctly at least in some way, people prefer the more talkative NPCs. Well, I agree with that too, if the NPCs don't really talk that much, it'd be better if you could create your own.
Exactly. The fun with roleplaying games is that the characters have something to say all the time, whether useful or not useful.
