This summer I grew more and more frustrated with my son and what he was doing every day... Very little (He did just turn 13) except for all the run around, shoot-em up steal a car-what ever 'video Games" then I went online to Amazon. Af least he likes to read, maybe a book? Then I saw Myst Revelation. I had loved the first three and because he is very analtical I decided to let him check it out. Well, the shoot-em up etc, etc, games have been shelved for about a month now. He gets to play for about1-1/2 to 2-hours a night and thinks this game is "soooo cool" besides a few glitches in some of the "puzzles" the graphics are amazing and the story line is even better.thank you,Ms. Loretto Christian
