The 11th Hour serves another set of great, although sometimes freakishly hard puzzles. This time there is also Stauf's demented riddles, that are quite often almost impossible to figure out on your own. Luckily there's the "GameBook", that gives you hints if/when you need them. After almost 20 years, The 7th Guest and The 11th Hour are both very original games, if you ask me. Definitely not for everyone, but I enjoy playing these brain teasers again and again :)
Definitely the best old HC-puzzle game I've ever played. Moving around is slow and sometimes even frustrating (you can't skip any movements or dialogues)... Still freaking awesome game people who like to play something else than COD for time to time :)
