I've fallen behind on playing my so-called "walking simulators" lately. I only recently completed "Dear Esther" and still need to get "The Talos Principle" and "The Witness" behind me. This title comes from a strong pedigree, and I'm sure the puzzles will confuse me to the end of my life.
The first Myst titles were so far ahead of their time, and really came at a special era in gaming. I'd love to see this game separate itself from the pack.
