I often hear that the main characters are made laconic or completely devoid of speech or emotions in order to make it easier for the player to associate themselves with them. To be honest, the older I get, the more it irritates rather than helps. It's okay if it's a shooter where there's no time for dialogue or exploration, but that's not uncommon even in story-heavy games. Are silent, impersonal heroes really better, or do you prefer to play the role of someone more alive?
