Theres more designs and discussion on this topic during an episode of a radio program from WNYC called Studio 360. In case anyone was interested.

The episode is "Monopoly Redesigned". It's WNYC story number is 135912.

(Also, my submission would be: "Everyone rolls at the same time (the Stack: Gov't Handout; Chance; Rent/Buy out; Auction; Jail). All property goes to immediately to auction (unless youre a "Friend of the People": you have at least one other property of that color which you landed on this turn; in which case, you can buy it out-right from the government if you like for the listed price.)

edit: (oh, and before play, everyone walks around outside and cuts out logos from litter to use as properties -- this shouldn't take more than five minutes or so no matter where you live)
