In the past I play many adventuregames! The "Myst"-set I found very good, except the last one of that set... But Myst I and Riven (Myst II) I found the best of that set ...
But I play now almost only RPG because it has a much better replayability than adventures (they have not or a little bit - after years not playing them!).
Puzzlegames I play sometimes too, for me also addictive!
I love the puzzles set in Divinity II, but the most of them are for me easy. But it's well-balanced in D II .. its is an RPG, not a puzzlegame or adventure. But I'm happy I can use my brains and not only hack and slash!
