JDV72: 1) Will the AGI version of IV be included?
Collector: I would highly doubt it. As I said, the AGI version is very rare and has nothing to offer over the SCI version
Actually AGI version does have some unique differences. Different artwork in some of the screens. Building construction of mansion is different, some of the screens have more plants and bushes for example. The AGI has a different script/text narration etc. There are a few extra things to look at in some places in the AGI version this includes some squirrels or random birds not found in the later SCI versions. Puzzles are largely the same, although time related puzzles function a bit differently IIRC?
Obviously the forementioned easter egg. I think there is also an additional PQ related easter egg in the mansion. Nothing particurarly special, just a certain bit text that pops up if you look at something the right way. Although I've never tested it, and it may just be something that was left in the game files, but not used. Kinda like the' kill King Edward' easter egg deaths (two versions), or the perverted description fo Valanice in KQ2.
