If you're looking for a good old school point-and-click adventure game, I highly recommend hunting down a copy of Torin's Passage: http://www.allowe.com/Torin/index.htm
Lowe designed the game so he could play it with his daughter - he's most famous for working on the baudy Leisure Suit Larry titles. That having been said, there's some sly humor there that only adults will understand. But at heart, it's a fun family game - there's even a hint system so little kids don't get too frustrated with it.
The Windows version never worked well even on Windows 95, but the DOS version should run perfectly in DosBox.
