Well, we do a short version and quit and a specific time unless we have all day (and night!). I passed out extra money to begin with. Sometimes i pass out properties like they're playing cards.
My strategy was to buy one of every color plus transportation. His was to build up the expensive ones near Go - Park Place and Boardwalk. ?? He had castles on those but i had traded him one of those for Cinderella AND 5 free turns on his property. (That's worth $1500-2000 each!) I put 5 playing pieces aside and put one back in each time i landed on his properties.
