it's just fun, what else can u say?
Basically, u were on a boat, it crashed, now ur on an island. You find a girl who has a little trouble getting around by herself, so when u travel with her, ur gonna have to hold her hand (literally).
It starts off a little weird, becuz for the first 2-4 days in the game, ur forced to just pick stuff up off of the ground.
then u can spearfish for food using a fun, but hard to get used to, touch screen mini game.
a few days after that u'll get into the cave in the waterfall and now u can hunt, make traps, use a fishing rod, and build furniture.
there are plenty of options of things to do in this game. ur cave will start off a little empty, but soon u'll have a basket to make ropes, a basket to make small traps, a water storage, firewood storage, shelves, and more.
the world in the game isn't too big, but traveling from ur cave to the cave behind the waterfall takes 3 minutes, so it is a little tedious as gamespot says, but not that bad.
if ur looking for a game that takes full advantage of the touch screen that is just plain fun, u'll find this game to fit into ur collection.
