Gremmi: I've bought it regardless as the series is easily my favourite ever (GK2 is my number one game of all time), but can anyone confirm if it's the 640x480 resolution version or the 320x240 one?
The game was originally released as 320x240, but parts of it (the GUI, cutscenes and close-ups during conversations) were remastered at 640x480 for the CD release.
Hm, here's something from "The Countdown Has Started." thread, post #1978 by Protoss:
"It's the full talkie version of Gabriel Knight!"
And that would mean the CD version.
Besides GOG always tries to do their best with their releases, so it had to be the CD. ;D
