Some Good news for Samurai Battles, according to Richard Borg on Boardgame Geek, GMT will pick up/expend the game. Not clear what is coming, but it has to be better than the alternatives.

Re: Regarding need to expand Samurai Battles and Ninja Attack
As the saying goes... WAIT FOR IT!!!!
GMT is already on this and will be leading the charge soon!

Trying to better engage my son to play this game (Old Japan / Samurai Era doesn't look attractive to him) I've started creating some stickers (for wooden blocks) to create both Mordor and Free Peoples armies.

Next I've also adapted Command and Dragon cards and manged to create a Vassal module to be played online.

Here you can see a preview.

Below you will find all files created (consider actual Vassal Module as a "work in progress")
