If you arent going to release Naruto Shippuden: Ultimate Ninja 5 because of the prequel's sells its because the prequel didnt have advertisement, there were no tv commercials and therre wasnt an Naruto Shippuden broadcast on tv at that time...so RECONSIDER* if youre not releasing it
Well, its your fault, because UN4 wasn't advertised in UK and it sold amazingly well. I would assume we had storm and the name of the storm was a good ad for every ultimate ninja game, especially for those who only own ps2.
