For me, being a ninja was always about stealth ever since I first experienced Tenchu: Stealth Assassins. This game has it's own style and feel to it yet it pays homage to the stealth genre.
I've been waiting for a ninja stealth game like this for awhile now. The last decent ninja stealth game was Tenchu Z imo. While other games like the Shinobi series and the Ninja Gaiden series are fun action filled adventures in there own right, they never really appealed to me to the degree of the stealth based games.
It's nice to see a game company do something a little different in a 3D dominate game industry. The 2D idea was brilliant. Reminded me a bit of how Castlevania: Symphony of The Night was such a hit back on PS1 when everything was just starting to move into the 3D era, albeit this game is more for a niche crowd.
Hopefully the success of this game will bring more sequels along in the future.
Kudos to these developers =)
Faith is the substance of things hoped for but not seen.
