nice maps, ihmek. any interest in a historical map of china, mongolia and russia during the qing dynasy (ie, much of eastern eurasia but from the perspective of china's conquering armies)? there are a lot of great maps for this era [in this book](

also, if enemies or teammates play your japan map and get angry, they could settle it in [the dohyo, sumo style](
