The graphics and interface are vastly improved and the puzzles more organically connected to the game world; the game as a whole is far more compelling.
The game’s puzzles vary greatly in their difficulty; I was able to complete the puzzles of the Easter Island portion of the game within mere minutes, while the solution to the Mayan Pyramids eluded me for much longer. Tasks range from finding a crowbar and later using it to open a locked door, to manipulating the positions of giant stone statues to permit your passing an underground booby-trap.
If you’re a fan of gadgets, then look no further: this game’s for you. The Omega Stone is crammed to the brim with all sorts of goodies—you’ve got your typical everyday grappling hook, crowbar and detonator, and even some more exotic items such as an ancient mask that may offer more than your next Halloween costume.
If the thought of exploring some of our world’s most famous ruins and mysteries interests you, I encourage you to give The Omega Stone: Riddle of the Sphinx II a try.
