Dialogue

Mass Effect's dialogue is being touted as "the real star of the show." Instead of the traditional dialogue choices, which show you every word of your response verbatim, you are presented with choices that can be described as gut feelings. For example, one of your choices may be "Don't try to study me," but what your character actually says is "I'm not some artifact you can take back to your lab, doctor." You can even interrupt the NPC's dialogue, if you so choose, giving the game's conversations a much more natural feel.
