Bought this today and decided to put it together in the evening.  Although the directions say "two people" to assemble, I try to do everything myself.  Would have been a bit easier for the first 15 minutes with help.  It took about an hour and a half by myself.  Much of the time was spent removing the platic protection on each piece after I completed the build.
I am truly imressed by the quality of the product and the genius of the design.  Everything went together so easily once I got rolling.  I am 70+ and have six grandchildren (and a grandmother) who will playing this game for a long time to come.
Thanks and keep up the good work.
