Lol we actually used to play this way with my cousins. We had two younger cousins that weren’t too bright at the time, but really wanted to play. So they played as “peons” and got a pawn from a chess set as their marker. They got an extra $100 for passing go, but that’s it. They couldn’t buy or anything, only pay. They actually seemed to have fun in a little competition between themselves as to who could weather the capitalist hell hole the best.
