King's Quest III: To Heir is Human

The Good
Step from KQ1/2 regarding technical execution is significant. You play as a boy who want to escape his master-tyrant, wizard Manannan, who keeps him as his personal slave. The world is much bigger, there's clock running in the game and Manannan follows his schedule (and you must time your actions to fit into this schedule), writing is better than KQ1/2, story is more mature compared to predecessors, and there's even some magic doing.

The Bad
So why just 3*, when the game is technically better at almost everything?

Answer is: difficulty. No, puzzles are not just "challenging". I beat Gabriel Knight trilogy, I beat Indy Jones 4, Monkey Island or Day of the Tentacle. So no, I'm not particularly pampered regarding adventure games. But KQ3 is VEEERY difficult, unforgiving, and it takes probably weeks, maybe months to beat it without walkthrough.

What's worse, there are lot of dull points. You have to walk lot of times long walks up and down the hill, and you have to do it, because of this time scheduling already mentioned. One walk is like 5 minutes or so of dull walking, and you'll have to repeat it several times. And if you DARE to beat the game without walkthrough, it's guaranteed that you will have to restart game (or return to very early save points) maybe dozen of times, so in the end this dull walking can stretch to hours of net time.

I can't imagine someone spending that amount of time and energy today on 1986 adventure game. Most of positive reviews here are nostalgia-driven. In those times when good games were scarce, you didn't mind playing one title for weeks or months, talk with your friends about progress in school or work, exchange ideas, and then move a bit forward if you learned something new. Such nostalgia is understandable. But if you look at the game from the point of view of 2023 gamer, who wants to play KQ3 for the first time, you're just not going to enjoy it so much because it's frustrating. I beat and enjoyed KQ1 and KQ2 in "modern times" for the first time, because difficulty was ok, and I not spoiled those games for me by always looking into walkthrough. But KQ3, I just gave up, I finished the game with walkthrough help, just to have it finished. Even when playing with walkthrough I was still amazed by difficulty of those puzzles and I knew that this is just way too much. So in the end, my memories for KQ1/2 remained way more positive than for KQ3.

The Bottom Line
You can play KQ1/2 and enjoy them and beat them even today with none or just few looks into walkthrough. This can't be said for KQ3. The game is technically excellent, but exorbitant difficulty just doesn't allow me to give it higher score.
