Just picked up Professor Layton and the Mysterious Village for the DS today. It's basically a point and click adventure game, but every interaction with a towns person will present you with a logic puzzle. Not the crazy old school Lucas Arts style (Hose + Balloon + Dog = Boat) but rather TRUE logic puzzles. Think more along the lines of Brain Age type stuff. Anyway, it's alot of fun, and the gaming press has been giving it some great reviews as well. If you're looking for something to stretch your brain a bit, pick it up, you won't regret it. PS. Some of the later puzzles, as well as the download puzzles, are INCREDIBLY hard...if you get frustrated easily you might want to find another game.
