Thanks for doing this again, flotsam.
There's only one change in my list from last year. Of the games I finished (some older, some newer), I only liked one (an older one) well enough to let it replace one of my other favorites.
The first 2 are my top two favorites, the others are alphabetical.
Myst II: Riven
Beyond Atlantis (aka Atlantis II)
Broken Sword 1, Circle of Blood
Broken Sword 2, The Smoking Mirror
Kyrandia 1, Legand of
Monkey Island 1, Secret of
Myst III: Exile
Riddle of the Sphinx
Schizm (Mysterious Journey 1)
