again, i'm covering the 3 versions of the game i own, there's also a version 4, that i've played a few times....
all the versions of this are very similar, but as each new game comes out, you tend to get more controll of your army, and get better moves for your character.
set in the far east, many years ago, you choose a character to lead your army, then have various battles to fight, gaining points, hence extra powers, along the way...
every level is pretty much the same, fighting everyone in sight, in the early games, you only have 2 differend hits, jab and slash, but in versions 3 and 4, you get to pull off 'tekken' style moves with the weapon of your choice.
to watch, the game looks boring, but when you play, the fact that it's very repetative is soon forgotten as you win battle after battle, defeating all enemies along your journey..
if you are going out to buy this game, i'd suggest you go for version 3 or 4, having much more freedom in fighting, it's pointless owning more than one version, because they are very similar, your doing exactly the same in each game
overall, i'd give this 8/10, ((7/10 for versions 1 & 2))
