I bought every Adam's Venture game for $1.74. Ill tell you this, I wish I hadn't. The game itself goes on for maybe 1 hour or 2, and just feels like a very cheap knock off of Uncharted. As for the story, heres how it goes: You are Adam Venture (sooo funny) and with your girlfriend Eve, you go in search of the lost garden of Eden. Aside from the not-so-subtle Biblical references, the game throws passages from the bible at you via word puzzles, which honestly are too easy to be called puzzles. And even so, the puzzles might be the best thing about it; the controls for this game are worse than Tomb Raider (1996), and that's saying something for a game released in 2009. The graphics leave something to be desired, though the pretty shading and lighting effects from Unreal Engine 3 makes the bland, low quality meshes and textures look somewhat decent, and defintely more appealing than the animation, voice acting and the lip-syncing.
Overall, if you could spend your money on anything else, spend it on that. This game is just a cheap, preachy excuse for a game.
