I genuinely don't understand why people are upset with this? There's so much we don't know about Ada and what her life looked like previously or what it is now currently. There are so many perfect opportunities to create a solo game for her.
@yuukuna_ Her actions, choices, goals, motives, and her conflicts all progess both stories foward. Excluding RE2 Ada has never been seen as antagonist in either RE4 or 6. Infact in both games she goes out of her way to ensure the safety of the main characters directly contradicting.
