Well my ultimate favorite still remains a "6" board game of Monopoly.
Basically you get those little colored dot stickers, you put one color on each space on a board and put the same sticker on the cards for that board so that you know which belong to which.
Then the whole group decides before the game starts what path you will have to take to traverse the 6 boards, it's not as simple as just going around the edge spaces, sometimes you will have the player decide that you must traverse every single board in a circle before proceeding to the next board and other times it may only be one or two boards that you have to traverse, other times you may actually end up going backwards on a board. This is layed out on paper so that everybody can easily reference the path that you have to take. Optionally you can also get or make little arrow stickers and place them around the board so that you know what path you have to take, usually makes it much easier unless you just use paper with an arrow on it and somebody decides to turn it or it gets blown off the board. But as long as you have the path down on paper it's easy enough to replace the marker showing the path on the board.
After that it just turns into a big jumble of fun for us, trying to get property in areas that we think people will most likely land based on the path that we've chosen to traverse the boards.
Monopoly isn't for everybody, in fact I have a lot of friends that find it frightfully boring but who have joined us in our 6 board game and enjoyed it, at least for a while until they started to lose and then get bored with playing it.
Sadly, we haven't gotten enough people together in a long long time to play this way, many friends move away to other cities, other states, other countries.
Edit: Oh and you also start out with more money, depending on how many boards you use will depend on the starting cash that you start out with. Raise or lower it to make the game easier or more difficult. You can also change things up by adding extra dice to the mix so that it's less predictable on where the players might actually land, at least until you try to figure out a pattern of dice rolls that happen more frequently than others, although still random due to die roll.
