Naruto Shippuuden Manga and/or Ultimate Ninja Storm series

I feel like I'm spoiling the chapter for others that want to read it, but haven't... I liked seeing the first Hokage's personality. Plus, we found out why the Uchiha are cursed, and why their eyes change.

Yes, I know what you mean and don't worry about spoiling for me, I read every chapter the day of release. However, I can understand not wanting to spoil for other people. And yes, the same for me, the first Hokage has a interesting personality for someone as powerful as he. If the second has massive power with just the twitch of his finger, not close to his full power. And the first is supposed to be strong than the second, just how powerful is the first? And then there is the Sage of Six Paths that make both Hokage look like toddlers, what's his power? :o
