I can think of a few ways it could be better shifted to the modern audience without tarnishing the spirit of it:
-Make the vistas that don't require a specific post a little bigger.
-Make the riddles more clear about what time you need to show up/don't require a specific time for the ones that don't seem to have any in the riddle.
-Remove the weather requirement for interiors where it won't be seen.
-Don't line up the weather changes with time requirements.
Other than that, the only issue I ran into was an instance where /pray didn't work when I typed it, but worked fine when I selected it from the menu.
Also, as an asside, this thing about "jump puzzles" (my people call it "platforming") doesn't excite me. This game has terrible twitch jump controls.
