Unfortunatly, there is no Twilight edition of Monopoly. That doesnt mean you can not have one though! Making a twilight monopoly is the best way to freshen up on your twilght saga facts. Here is a list of things you will need to create a Twilight Monopoly (remember everyone has different ideas so you may need more items that are not on this list):
1. Determine the street names for your version. It helps to assign each of the colored sets as a neighborhood. Some examples are Charlie's house, Forks high school, the forest, the Cullens house, etc.
2. Sort out which streets will go where. Make the places realistcally match the prices in Monopoly. Some more expensive places might be Volterra or Isle Esme. Another idea is to make them twilight characters or twilight items such as necklaces and gifts. For the railroads, a good idea is the four books.
3. Decide which, if any, rules you will change. In some versions, you can take out loans from the bank, in some property can't be owned, and in some there are two parts to demonstraight the economy.Keep in mind that if the propert values and rules match monopoly's, your game will play well. If you choose to do people, you may want to change the rules so that players are not owning characters.
4.Make your Chance and Community Chest cards (you can rename those as well). Give the carsd new slogans and ilustrations but dont change what the card actually does. For example, when there is a card says 'Advance to Pall Mall', you could write 'Advance to Bella's House'. But if making community chest cards, you can make things up so instead of 'Pay school fees', you can write 'Pay Jacob to pass the boarder into quillette territory' or something similar. You can make pretty nice ones by cutting the standard 5" by 3" index cards in half.
5. Design your money. It is best to do this on the computer and print them because drawing each one may take a while. Personlize them by having a picture of Stephenie Meyer on them or just call them Twilight Money. Also consider that it might be easier to just use the cash form the game, or buy a replacement set from the game story.
6. Build the houses and hotels. If you want to model them yourself, you can use Fimo or sculpey clay. Otherwise, you can just use Monopoly houses and hotels. Adding more then just two possibilities may make the game last longer.
7. Make Realty Cards for your properties. Use the same rent and mortgages as the corresonding original cards or written/ typed on to new cards using halved index cards.
8. Design and draw out your board. It is easiest if it has the same size and layout as the real board. Use heavy cloth or cardboard (a posterboard even works).
9. Make playing pieces (tokens) from sculpting clay or use small plastic or metal figurines or the monopoly figurines. Another idea is to make the pieces Twilight characters.

Apparently you can customise your own board as well at https://www.mymonopoly.com , however I am not sure how much you can change the board. Making it yourself may be easier!
