Gzz, some people.
Comparing this to Monkey Island is nonsense. Maye Discworld would suffice with all the sorcery, but still not the same at all. And Monkey Island 2 was BAD. I mean really bad. All the gamers hated it, the series almost got finished because of the hugh dislike it got.
If I'd want to criticise that list further, I'd say Indiana Jones had terrible interface, King's Quest was EGA and the text-based interface I hated (and the later parts were too candy in story), Laisure Suit Larry (whatever the spelling is) could be really blamed for being random and nonsense in the field of puzzles, and Space Quest was just another "Quests of Sierra" clone.
But as I don't want, I'll just leave that on you
