There are many people who can be defined by their actions rather than their words. Many of our favourite game characters allow themselves to be seen in such a way by never uttering a single word. Although that was back in the era when talking in games was either all through text or sounded like someone had taken a cheese grater to their larynx.
Today, nearly all popular video game characters talk. It’s even seen as a little strange if they don’t. In fact, some of them never seem to shut up, which makes quite the contrast when you do find a silent protagonist in a current-era game.
