Query: A bit too easy if you like the challenge of Myst, Riven

This is an excellent game for the novice. The puzzles are relatively easy and provide a good introduction before venturing on to more mentally intense games. I can't say for certain that I'm not a bit biased - my first game ever played was Myst, then Riven. It seems all the games I've played since then simply don't measure up. Journeyman Project 3 was just not challenging enough.
