You need to factor in frequency of landing and cost to build. Orange is in the sweetspot. IIRC, red gets landed on more often, but the extra $50/house makes it

You need to factor in frequency of landing and cost to build. Orange is in the sweetspot. IIRC, red gets landed on more often, but the extra $50/house makes it tough to build up. Green is crap on both accounts. Pink is less frequent but cheap to build. Light blue and purple are only good if you monopolize early and can drive a building shortage (get ready to be yelled at by anyone not intimately familiar with the rules). Boardwalk is mostly useful to tilt the balance in your favor on long games. (as you pass go and collect chance cards, $ in circulation go up over time, so it gets harder to bankrupt people)
