Bought Taiko sometime last year and been playing a bit of 6mm with some friends. Really fun game. With 6mm and the way Taiko works there are a lot o models that end up being played on the board, so movement can take a while. Combat however is quick and easy to understand. There is a in depth moral system that effects all parts of the battle. Seiges are hard as hell.
There can be a few problems, and some need for rule clarifications, but overall, Taiko is a Fun, effective and fast Stratagy game. 4/5
