Nah, I've literally only just started playing Medieval II today. I got the original Shogun and it went so far over my head it scared me off the series, but I got M2 free a while ago and gave it a go for the Hyrule: Total War mod (which is still downloading VERY SLOWLY as I type this)
I still got confused by the tutorial though. This series really isn't my cup of tea.
