I made a monopoly map long ago, but i used up ALL the strings available...and didnt turn out to be..."great"
What i made possible, 3 players
no chance/community chest/electical/waterworks
Every whole section (eg: park and broadway) could only maintain 1 building (as in no 4 houses and hotel)
i only made 2 dices add up to 6 movement (1,2,3 and 1,2,3)
The reason why it took so many triggers is because the aspects of movement.
---Being as close as possible to the boardgame, movement was very hard to do cause of the varriation of the rolls.
If you start out at GO and roll the dice (using mine you have 5 options of movement)
With 5 triggers per Single space for movement, you have about say ~ 35 spaces to move from. So thats 5 X 35 triggers X 3 players= 525 triggers
THEN you need to have a Yes/No purchase or Payment for each slot which you can purchase. Lets say thats 28 places. THUS 525 + (28 x 3options x 3players) = 777 triggers.
... THEN you gotta do the payment trigger for each slot AND payment for each slot if they have a house. So 28 places x 3players + 24 places X 3 players with houses = 156 triggers... total of 933 triggers. Now you can add about ~50 triggers for the Dice and hitting Go and going to jail and staying for the turns. which brings you to a total of ~1000 triggers.
Even adding a simple space as in electical/water works would increase the total dramatically.
Sorry for the long wind but, to make a monopoly map is possible. Near the original... impossible
