Yes, it is a great game. It was hard to figure out the puzzles like: the drums in Nahele Rain, the puzzle in the pond in Hyaku Lake, 2 puzzles in The Desert of Naar and of course the puzzles in The Steps of Akasha.
An other one I liked very much is Quern, Undying Thoughts; Lake Ridden; The Eyes of Ara; The Painscreek Killings; Obduction; RoonSehv; ASA and Catyph.
In a little bit different genre: The House of Da Vinci; The Room 1 + 2.
And of course a couple of older games: Reah, Amerzone, all the Myst-games and there are more but I can't play them on W-10.
I probally have forgotten a lot of other games.
