Id like to see adult sherry as a protagonist; like Jill with the nemesis virus, the antidote to the G-virus only put it into a dormant state, yet when it awoke (thanks to Wesker) she gained all superhuman strength but without mutation? the game could start with Ada Wong breaking into where ever Sherry is and rescuing her, if Wesker had her locked up somewhere it would be cool if you have to try and sneak out without being seen by either a B.O.W or a group of ZOMBIES, but then one sees you and all you have to do is just run! and if you slow down, your dead. Threw the game Sherry is struggling to control her powers, (or shes already done that while being locked up) and later they meet up with Leon in England (Zombie outbreak) to try and stop another Bio Terrorist. -_-
I hope that all made sense! lol
