I think it was the most recent jar time with Jeff where he mentioned that he thought the era of silent protagonists in games was over. I agree that this is dated trope, but it led me to ponder about the exceptions to this - the games where main protagonist has a personality and expresses thoughts and feelings throughout the game.
I've not finished Far Cry 3 yet, but at the moment there feels like a little bit of dissonance between what I am feeling as the player and what the character is feeling. Jason Brody is constantly moaning about finding his asshole friends and is worried about where they are.. but I am having a fucking awesome time machine gunning sharks. The games that do feature a protagonist with personality seem often to have the protagonist not having a particularly great time (while you the player, presumably, are), like Marcus in Gears of War or even Shephard in Mass Effect.
I'm certainly not saying this is a 'bad' thing, I get that tension and drama are integral parts of a story. But how many games are there where the main protagonist is actively enjoying the thing that you the player are doing? I can only think Duke Nukem 3D, and certain segments of Serious Sam.. I guess Guybrush Threepwood kinda 'enjoys' what he's doing? At least in SOMI, where he's becoming a pirate.
