But why on earth do they pick Frankto's Naruto d20 system to do it with? It's a thousand and twenty-four page supplement to another complete, already rather rules-heavy RPG system. Whole bolt-on subsystems interact in complex and difficult-to-predict ways with the existing rules and each other- Chakra, Techniques, Shinobi Skills, Strength and Speed Ranks, the Hostage Maneuver rules, Power Units...it's like d20 Modern with Exalted bolted on. It's insane. I would be ecstatic to play in a Naruto game run in a system that actually makes sense for it, like Mutants and Masterminds. Even D&D 3.5's psionics rules do a far more elegant job of it than that ungodly chunk of rules. What's the deal?
