I'm always surprised to hear about people's problems with Clear Sky. Because nobody ever echoes the problem I had with it.
It's pitch black at night. And no way to skip through night. So it's just wandering around, bumping into rocks, or hanging out at a camp for an hour or longer of real time. The actual length of time escapes me, because the second time night came around, I stopped playing the game altogether.
I really do need to play CoP. I own it, but it's on the pile.
By insert-deity-of-choice, I think you may be right! That's an observation I never quite caught.
Then again, I never minded linear design. It's not usually as bad as the op's image illustrates.
