I've sort of given up on the series, for pretty much the reasons you listed. It
seems things just keep getting added to Harvest Moon that it doesn't need. Like
a plot.

What happened to "your grandpa died and left you a crappy run down farm. Its
up to you to fix it up!" Thats all the plot Harvest Moon needs.

Harvest Moon 64 was good as well. It's sort of the cut off point where HM just
sorta lost its way.
