I know Navi is the obvious one here ("Hey, listen!") But what are some other ones in your opinion.
My vote is for Fiona from Mercenaries 2 ("If you're ever feeling a little lost, come back to the PMC and talk to me, I might be able to offer suggestions.") She never has suggestions. She also gives the SAME damn description every time you drive into a city even if you've been there a thousand times already.
There's also Roman from GTA IV ("Cousin...let's go bowling.")
