Judging from some of the weird & crazy posts I've read lately about the game, if Larian revised the manual few would be able to read it. Of those capable of reading on a 6th-grade level, fewer still would comprehend it. I mean, they are clearly struggling mightily with the current manual and have obviously turned off the game's on-line tutorials (you know, the folks who think three consecutive sentences is a "wall of text," etc.)
It's sad, but for some people, once you go past "point & click" it all becomes much too difficult. (And people say there's no truth to the fact that Western civilization is headed back into another dark age! Psssshaw....;))
