same here...in my very first game, too:
we had a jerry lee lewis start (come on over baby, whole lot of heavy land-auctioning going on),
so by round 10 there were only 3 plots left...
imagine my surprise when i got _all of 'em_ ! in round 10, 11 and 12 - the a.i. players were content with assaying the empty plots, but displayed no interest whatsoever in actually aquiring them.
as i should NOT have to mention

this a.i. behaviour might not entirely be appreciated by the large majority of prospective players....
