Are you a fan of the Lord of the Rings series? Then you definitely need to pick up The Hobbit, to learn how Bilbo found that magical ring.
There's the usual mix of strange mindless quests and puzzles. You fetch medicine, carry messages, and give assistance. But it never gets tedious - you're always learning something new about your abilities and stretching your brain to figure out how to get through a puzzle.
The game is nice in its pathway. You don't waste hours trying to roam the entire map figuring out what to do next. It's usually fairly obvious which WAY to go next, but it's up to you to figure out how to get there. For people who haven't read the hobbit, it's a good way to get a background on who Bilbo is, how the ring was found and what the world was like in the years before the Lord of the Rings series.
The graphics are reasonably OK for a GBA - I did have to complain about the pink insides of the hobbit homes! But still you usually can figure out what everything on the screen is pretty easily.
Not really a game with high replayability, but with Tolkein being so popular right now, you should find it easy to find some friends to trade it with when you're done!
