Warning: This post is for you, even if you are not a gamer/anime freak.
Unless you lived under a rock, like me, you probably heard about Professor Layton games for Nintendo DS. I just started it yesterday. I'm in the 7th riddle (very beginning). It is an adventure game that requires you to solve small riddles, unrelated to the story, in order to progress. The game has an inexplicable charisma.
I strongly recommend it. Even if you are not a gamer.
