Given how ultra cheesy most game dialogue is I'd rather the whole game remained quiet from a voice perspective. I mean did you hear Sonic in his intro movie? Made me cringe.
There are very few exceptions to this rule. Half-Life 1, HK-47's dialogue from KOTOR, Operation: Flashpoint off the top of my head. It doesn't mean a lot of games suck, just means I think some would be a lot better off if they went the Shadow of the Colossus route. One of the things that made it so epic and beautiful was its silence.
