I'm playing on a PC connected to a 60" TV and sitting about 8 feet back from it. While the game looks great, the default UI and font size are just a bit too small for me to make out the details at that distance. Fortunately, there are options to scale up the UI and adjust the log size, so this isn't really an issue... except that neither of these things affect the NPC chat window size, so I have to lean forward and squint to read what's going on whenever I talk to an NPC.
I could see this also being a problem for people who have physically small but high resolution monitors, or for people with poor eyesight. Would it be possible to have the NPC chat window scale with the rest of the UI, or add a separate option just for adjusting its scale?
