I noticed the tabs for realMyst and Riven in Drizzle. I expect eventually those will be importable into Uru via Drizzle.
Now I wonder about Revelation and Exile, mainly Revelation. I want to visit Tomahna in Uru. I expect the Ubi file structures are not similar to those used by Cyan. But is it a possibility that somewhere down the road that, I don't really expect any time soon let alone this year, we might be able to visit either the Exile or Revelation ages.
