Don't know the Myst-like universe unfortunately (never played one).
I'd like to know if the game you"re making will have some quest where you must know
about the Myst universe or is it possible to play without even knowing (or have played once) a Myst game ?
If it don't require any knowledge about previous game, and that every answer is findable
in the game, then I'll surely try it once
I'd like to help with the translating (english/dutch) but unfortunately I can't say I'm good with those languages.
I'm very used to read those languages and to use it commonly, but not to translate in a "supported" manner
(to translate it with novel like sentences ... like "Thou haveth ne'er known thy truth")
Well you can always send me some text and I can always give it a try, but cannot promise that I'll help.
