So. Romance of the Three Kingdoms, part TEN.

I remember the first one, and I played III on the Genesis briefly. Not a bad game but nothing I could really get into. I can't imagine TEN of them, and from what I've seen, there isn't very much different between these as they're released.

So... fans of the series, how into this game ARE you? Are they really that different? What have the major breakthroughs been? Was there a "standout" version?

Most interesting to me is... how MANY of them have you actually played?
