Never before has a ninja been so slow, but been able to save the world twice. I miss you Tatsumaru, why did you have to die?! But I dunno, I have been kinda depressed by ninja games lately. I beat every possible aspect of Wrath of Heaven, and I even got the ending where Rikimaru takes off his mask, but I really think its just a mediocre game. Shinobi was fun, but just too insanely difficult. I really found Ninja Gaiden to be overrated, while its got slick graphics and nifty moves that flow nicely, the controls just weren't perfect, the camera got pretty annoying and the difficulty level was also too steep.
I'm not against hard I games, but I believe a game should always be beatable.
