I know that the franchise was ruined in later releases but for me the first two Tenchus were fantastic games. You could play the game as a straight up action game but your character wasn't really equipped to deal with the guards head to head. Playing the game stealthily opened the game up a lot. You could run on rooftops, kill from the shadows, disguise yourself and even teleport. I had a lot of fun with those games, especially the first one. The biggest flaw from those games were the boss fights. I wish the game let you stealth kill the bosses but you usually had to fight them head to head.
