There're people who love the Myst games. I play to the end Myst, Riven (Myst II) and Myst III. I find the puzzles are logic... these game are old school games, so you must write down on a pice of paper (everything) that can possible help you solve the puzzles... wink
The first games I played in my life are such games like Myst and other adventures.
From the time I discovered Divine Divinity and other RPG's later on, I love much more playing a RPG and forgot further playing adventure games ... because I love the replayability of a RPG ! Adventures have avery low or just none replayability !

For a RPG it is fun there'are some puzzle in it (but hope de dev's don't make only puzzle for making the playtime of their game longer! )
and I agree that the most difficult puzzles may NOT stand in the way of the main quest/path to complete your RPG !
The most great puzzle in Ego Draconis I found is the statue puzzle in Keara's Fortress! And you can end the game without solve that puzzle, so that's okay wink


On 7th of february 2015 : I start a new adventure in the Divinity world of Original Sin,
