If you haven't yet, you should play Pentiment. It's set in the early 1500s as the printing press is spreading across Europe, and each character's dialog text reflects how they would write (or print, for the people who operate presses). The text rendering is truly beautifully done, the ink dries a few moments after the text is written out and everything. I've been hoping for a technical blog on their text rendering techniques but haven't seen one yet.
