You might have read my review of Treasure Seekers by Artogon Games. If you did, you know that I think very highly of the game, and of Artogon's original take on the HOG genre.
The Mystery of the Crystal Portal is another game from Artogon using the same engine as was seen in the Treasure Seekers games, but until now, it hasn't been available from Big Fish. I played a good portion of the game elsewhere in the past and found that it offers more of the same goodness.
So, if you like the Treasure Seekers games, you'd better give The Mystery of the Crystal Portal a try, now that it has arrived at Big Fish. The graphics are beautiful, the music is good, and the gameplay is what you'd expect from Artogon. This is a great selection for the HOG crowd.
