_ChaosFox_: Same here.
Part of the problem lies in the absolutism of puzzles in P&C adventures. In real life, if there's a problem to be solved, there's usually more than one solution to it. If you want to get a ball down from a tree, you can throw stones at it, climb the tree, prod it down with a very long stick or whatever. If it was a LucasArts adventure, you would probably have to make a pendulum out of a stick, a stone and a piece of string, attach a balloon to it, let it float up the tree and knock the ball down.
I'll be honest - I don't like LucasArts adventures. I find them illogical and I detest the way that they hold singular solutions to be absolute. As you say, Daedalic has the same problem. WadJet Eye went in the other direction - the puzzles were absolutely logical, but at the same time, that made them incredibly easy, because only having one solution meant that you had to be nudged to that single solution.
Daedalic's games usually have quite sensible puzzles. The Whispered World is really the only one that I had major issues with. Chains of Satinav, Memoria, New Beginning, Alcatraz, Deponia 2 & 3 and Harvey's New Eyes I completed without any need for hints or walkthrougs, and I had only a few problematic moments in Anna's Quest, the first Deponia, Night of the Rabbit and the first Edna & Harvey (and if I were more patient I'd probably get around most of those on my own too).
LucasArts classic's are a mixed bag for me. Secret of Monkey Island is their best work far as I'm concerned. Monkey Island 2 does have some terrible puzzles (though not the wrench one, I actually figured it out almost immediately) but overall is still a good game. The Dig slowly goes from very sensible to completely idiotic, and I got to pretty much hate the game by the time I reached the end. Sam & Max Hit the Road has pretty terrible puzzles too. There's a lot to like about it, but the puzzles are mostly way to insane to be fun to figure them out. Grim Fandango is sort of reverse-Dig for me, it starts out pretty bad, but in the latter half of the game the puzzles actually make much more sense. I still have not played Fate of Atlantis, Full Throttle and Day of the Tentacle (though at least I own the last one, and will geto to it soon).
Still, in terms of puzzles I really don't think there is a worse game than the first Discworld. The graphics and the voice acting is all top-notch, but the puzzles are not just illogical, they are cruel and demented. Even for someone who knows the books. Someone once said that to finish the Discworld without a walkthrough is to see the face of god - a cruel, insane god, and that's a spot on description.
