I believe the theory is that you to take the first game under discussion you can do things like blow up the bell tower and leave it a ruin up there. Its kind of entertaining even if it isn't the most useful thing in the world. Also the ones that you can never go wrong can be brute forced to a certain extent (thoguh I guess those that need timing based stuff that is less true of) whereas the ones where there are false paths does lead to asking if this situation is right and if not redoing.

I suspect it is a subjective thing really since I'm sure the guy who wrote the thing I saw wasn't lieing about enjoying it. From my point of view though I do agree with you. That may be because I'm bad enough at these things already without having the option to go wrong without noticing. :)
