Well, I beat the Secret of Monkey Island.
I'm kind of blah about it. The characters were goofy and fun. Insult sword fighting lived up to it's legendary reputation. Solving the puzzles in Part 1 was fairly fun and intuitive for me. After that things went off the rails rather quickly.
I remember when I was a kid, and I was playing Zork: Grand Inquisitor, all of a sudden Zork Logic kicked in for me, and I was solving puzzles left and right. That never happened for me in the back half of Monkey Island. I'd get stuck, think I had tried everything, then give up and read a hint guide. At that point I either got mad because I had tried the solution and it didn't work (like getting a certain bottle of grog in Part III), or my heart immediately sank because I didn't even know that was a thing I could do (like talking to inventory items). Or maybe it was the structure of Part II and III versus Part I. In Part I I had three different tasks I could approach more or less independently. If I got stuck on one, I could make progress in another. After that, things get very linear, and if I'm not solving the problem directly in front of me, I'm not doing anything.
Maybe it's just me. I'm old now. My brain has ossified by 2 decades of formal logic in my job. Maybe if I'd tried to play Zork: GI today, the Zork Logic that clicked for me as a kid would have been forever out of my reach as well.
