When I was a young boy, I used to read a lot of magazines about computers. It was in the mid 80's (now I am 35) and all that technological stuff was something new to me and I have to admit, I was very excited by the whole thing. For various reasons, adventure games become my favorite game genre although in the end, I managed to play very few of them alongside with the date of the original releases. After high school, I went to college (1997), and computers were left aside. But 7 years ago, with the rise of the amazing DosBox utility and the abandon ware style, sites (and due to the huge amount of spare time I have and the "nostalgia" thing), I managed to play (and finish) a lot of classic and non classic adventure games (even some text-graphic adventures like the "Spell casting" series). Of course, I always made use of a walk through in order to solve them. After playing hundreds of them, I came up to a conclusion: I wasn't anymore excited about those games. But the worst thing (and what I want to share with you guys) was that I realized that the whole "creating the "perfect" puzzle is something fake/illusionistic". It is human-impossible, a perfect puzzle to be created. Because puzzles, will be either illogical (according to common sense/not realistic), very difficult to solve them / lucky guess to solve them OR realistic but very easy to solve them a.k.a. "just click to see what is next".
So, the bottom line is that (in my opinion) adventure games were the finest example of showing off the power of the previous decades, computer systems, but for the modern days, the only thing that remains is a niche genre for the so called "hunters of nostalgia" or for those who are fans of the movies or for those who totally hate games which require quick reflexes or a strategic brain or rpg atmosphere. Anyway, I think you got the point
