I noticed this thread while idly scrolling down and thought...good grief, it was one of the few games I had on my PC that I used to play again and again even after completing it with every clan. I agree with everything everyone's already said, but I particularly miss the movies, the way the AI really could hand you your head when it wanted to, and the less 'Bill Gates' style of economy...every koku counts, instead of MTW where you're so rich it's silly, long before the end of the game.
But most of all I miss...
'My lord, your enemy's taisho fears for his life! He is running like a whipped dog!'

And that movie where the assassin gets to chop the geisha had me cheering every time...phew, saved the clan again.

(ps, Martok...how could you?Are you so easily seduced by the lure of cheap fake-half-timbered castles with 'Dunroamin' written on the front? Play a proper clan, like the Takeda )
