Another favourite board game of mine is CashFlow by Robert Kiyosaki. Ingredients: a game master, at least 3 players, game papers (included, but can be reprinted easily), calculators, pencils and erasers and 3 hours of free time. This game is educational! And I'm usually the game master. Muha. None of them need a battery. (okay, the calculator does, but I'm sure most of you can add two numbers on paper - plus the simpler calculators can run without batteries if enough light is provided - Dan)

Dan - And just to add some of my info to this post, here're my takes on the subject (and also, adding some pictures for the viewer's sake, and labels for Google, because, frankly, Google needs love too).
So what's my favourite tabletop game? The original Tabletop RPG games, of course. All you need is a book of rules, a trunkload of imagination, a game(or quest)master, paper, light, dice (6, 10, 20 sided - depending on the actual game you're playing) and some friends to play with. If you have no idea how this may look like, imagine you are in the world of Lord of the Rings. Imagine you are a soldier, equipped with some awesome elf-sword in a mithril armor, fighting the hordes of Uruk-hai. Did that? Good! At this point, after having your character created and written down, the gamemaster takes over and he tells you what actually happens in the world he created, what quests you may take, who you meet, who you fight. It can be an incredibly fun game to play, and it may even enhance your imagination!
Dan out.
