Nice to see you here!
The Book of Unwritten Tales is also available for download from GOG.
There is a new Nancy Drew game in the works which will be released on November 19th; preorders start October 1st. The game is called Midnight in Salem. Not sure if the game will be mouse and keyboard or mouse only, as they have switched to a new game engine. Should know more in the coming weeks. I would also recommend Unavowed and Lamplight City, both available from GOG and Steam.
Unforeseen Incidents is a good point and click adventure that was released more recently and it is available as a download from Steam and from GOG.
