GOG is still bringing the hits (like Casey Kasem will always do in my heart) and has released
The Journeyman Project 2: Buried In Time. It was initially released in 1995 and was a first-person adventure game. There's time travel, challenging puzzles and even a cow landing on a human; all of this is available for
$5.99 of DRM-free digital goodness. How can you go wrong?
