Tenchu was one of the first stealth games, but besides that the games had an immediate "cool factor" because of stealth kills and the grappling hook. The first two games in the series had "tank controls", which meant that no matter where the character was on the screen pressing left and right would rotate the character in those direction, and pressing up and down would make the the character go forward or backwards. This was the accepted way for 3D games to move at the time, but by the time the third Tenchu game came out, they changed it so that controlling the character was relative to the camera.
