As much as I would like to have William Shakespeare enter the RPG and then proceed to do an arc focused on Verona's fueding families, I have to agree with Rain on this. This is a good reason why you don't see many Fate characters in crossover RPGs, let alone Nasuverse characters. Their powers are on another league. Anno's managed to get Medea accepted because she wasn't that powerful a Servant compared to the others and was heavily nerfed for the RPG.

While I like some of the abilities, I can see the potential brokenness of them. Like being able to be immune to all damage from his Self-Preservation to, from what I know from reading your description, mind-reading powers (he has to observe their backstory and tell it to them, after all), something that, while not completely broken, is difficult to translate into RP without having a huge exchange of PMs, something that might be too busywork for someone's main ability.
