In the introfic to EP, we have a case where at least a couple team members more or less get their brains eaten by evil(?) nanoswarms and possibly, who knows, being turned into agents of the evil(?) nanomachines on earth. The thing is the characters in question had backups off earth, and would be resleeved into new bodies, however since no one from the party made it back then they would NOT know that some of their egos had fallen into nanomachine hands. So, in EP there's the possibility that PCs may end up literally fighting versions of themselves, if they go on a mission that ends up like the intorfic mission went and their egos end up in enemy hands. This could be a good setup for some role playing, but needs to be handled right. Anyone have any ideas on having player characters fighting essentially themselves?
