I agree with MW except that land auction should be like _original_ meaning also slower increase in price.

To give the needed advantage to lower ranked players in land grant and development, the starts could be staggered by one second or so to guarantee at least one mule for them, and in case of few mules (<8 ) the development start interval could be the time it takes to develop one plot (to give the last player at least a chance to grab 2+ mules).
This would still change the original game but not that much, in my opinion. And the increase and game speed would compensate the slight deviation from the original.
