I grew up playing this game on my first Macintosh System 7 I believe, so expect nostalgia goggles. Fate of Atlantis is a point and click adventure game originally released in 1992 by LucasArts.
The story and atmosphere are on par with the best of the Indiana Jones movies. While the pixelated visuals are quite dated by today's standards I find I'm still so easily immersed into the game that I hardly notice. The voice acting was well done in the original, and it sounds like the audio quality might be better in this Steam release. The music is also dated digital sequences, but still good enough to hold the immersion and also sounds as if it's been improved.
Unlike many adventure games, there's a point where the story can take one of three routes: team up with Sophia, use your wits, or use your fists. Each branch takes the story in a different direction and to different locations, often not accessable in the other branches. Kids used to spread rumors of a different ending as well, but to my knowlege, no such thing exists. The mechanics are based on selecting one of the nine pre-selected verbs and clicking something in the world that you want to act that verb upon; for example, Using "Pick Up" on "Ancient Artifact".
If you love point and click adventure games, and somehow passed this one by, I'd say you're in for a treat as Fate of Atlantis is one of the best, if not THE best. Yeah, I went there.
