If you're curious about this game, the trailer will give you a pretty good idea of what to expect. Exploration and survival are the two primary factors here. Mapping out the island is a puzzle in itself, as you have to use known landmarks to triangulate your position through line of sight. You'll soon realize just how much thought went into designing the topology of the island for this task alone. The game also makes some of the best use of HDR lighting that I've ever seen. At different times of the day, it becomes necessary to a focus on your immediate environment, as letting your eyes adjust to the bright sky will soon render things much darker around the area you're in. You'll want to make good use of the daylight, because the nights are dark, and venturing out, even with a torch in hand, is not advisable. One thing I think some people might complain about with the game is the movement system. The player's movement is momentum based. Climbing a steep hill is slow, and contrariwise, running downhill can cause you to lose control, and even incur injury. You have to throttle your walk in order to account for the terrain, as well as your physical condition. If you're too weak or sick, you can easily get hurt, or even start to drown while swimming. Always pay attention to your character's condition and mind these environmental hazards. Although I'm still fairly early into the game, I'm enjoying it a lot thus far. It's a slow paced game that rewards patience and thought, and punishes haste. If all this sounds good to you, then definitely check it out.
