This series is a great one to own.  I only wish they'd put more out for the PS2.  I heard that Myst: Uru was too "big" to put on the PS2.  Whatever.  They were probably too lazy.  The last Myst game I played was Myst III:Exile.  I'm not a big fan on playing PC based games.  Especially after reading the hit and misses people were experiencing when trying to load Myst IV:Uru on their PCs.
