Not sure how many of your folks are interested in the Total War series, but I discovered this past weekend, to my great delight, that Shogun 2: Total War is in the making. I have had an interest in Japanese history (particularly Samurai, but then who isn't!) for some time now and I've been thinking with each new release in the Total War series that they should go back and redo Shogun. And now they are.
They've also gone to great lengths to try and mimic some of the artwork of the period too, so it's going to look really interesting.
