That....that makes a whole lot of sense...so who else then. I believe Saber as Agrias Oaks is a no brainer. who else...gonna think on this a bit.... Damn I would love for this game to happen.
You are not alone at that sentiment DugFin, you are not alone . . .
Sakura would be Alma (With Ajora being Dark Sakura) Ilya would be Ovelia (Thus Saber taking care of her at Fate route) Gil could be Folmarv Kirei could be Dycedarg Rin is a toughie but I guess she could be Meliadoul Lancer could Olan/Orran Durai Kuzuki and Medea could be Elmdore and his Assassin
Right On with Alma as Sakura. But I think Rin should be Ovelia given her being with EMIYA/Delita, and that she is of noble birth and good with magic and all....just a thought though. Also for Lancer.....well Alphonse Delacroix (priest that betrays Agrias and Ovelia in the beginning), should be played by Bazett since her/his zodiac stone turns her/him into Cúchulainn (the demon's name in the japanese version) which should make the one guiding him (Folmarv) Kotomine, and the demon possessing HIM Gilgamesh.....Or something like that.....
EDIT: made the whole thing a spoiler in case someone reads it who hasn't played the game, if that person is you, go play it now.
