RoTK-style gameplay based on the sengoku era... different form the "semi RTS" of the nobunaga's ambition series
too bad tactical games like that never arrives on the west
(DO NOT compare a game like RoTK with spectral force genesis... such foul comparsion will send you straight to hell)
by the way, the difference between the 3 games are the faction you control or each one cover one part of the sengoku era?
