I’ve voted for Maniac Mansion just because of the dead ends: The player don’t know that he can’t solve the game anymore and that makes the game very difficult to solve.
If I look only at the puzzles then Monkey Island 2 in hard mode and Day of the Tentacle were/are very difficult.
But my difficulty-meter might be heavily influenced by the fact that I have never (seriously) played “Zak” or the prequel of “Day of The Tentacle”.
They might be even more difficult, but it’s not easy to tell because even if I will not find Zak ultra-difficult now, I have to take in mind that I played The Dig when I was younger and less adventure-savvy.
It would be interesting to discuss why an adventure game is difficult.
A former Sierra employer has admitted that some Sierra games were made intentionally obtuse and illogical to sell more hint books.
You put there dead ends, a lot of sudden deaths, random puzzles, other artificial ways to increase the difficulty and the game becomes, technically, more difficult. But at what price?
It seems to me that many people who don’t know adventure games very well still think that PnC adventure games are illogical. Do PnC adventure games have a bad reputation?
Finally in 1989 a smart guy wrote This and things changed a bit, but you still can experience the aftermath of the “old way” to design games.
Really? I found it the easiest. Not challenging at all. OTOH I would never have finished Monkey 2 or even Monkey 1 without trying everything on everything. (Not to talk about Zak)
The only explanation I can think (as to why someone can find The Dig harder than others) is that, in the Dig, since you deal with alien technology, most puzzles do not involve “common knowledge” about the world, but on the contrary the “rules of the game” are given in the game itself. Maybe some people are good at reasoning from common knowledge, less good at applying rules just learned.
(BTW, I only like puzzles that involve common world knowledge, so the dig was my least favorite, though I liked the setting and story a lot)
It seems that the list is led by the first three games made by the company. I wonder if it is due to lack of experience and as a consequence a bad design.
@Nor_Treblig I’m not sure about this, because playing this games TODAY, with more experience ( and mor age ), this games keep going too difficult ( at least more difficult than the other of the list )
