Games with good dialogue? That''s a tough one, because it''s easy to confuse the quality of the voice acting with the quality of the writing. And a lot of games don''t have much dialogue to begin with.

(Digs through games...)

I''d suggest The Longest Journey as having good dialogue for the most part. Fairly standard plotting, but good lines.

I''d also suggest Discworld Noir, if only because of the style and tone.
