A sequel without gimmick mechanics and solid action/stealth mechanish that is a hard M rating with nudity would sell.
>Do a "death by degrees" sequel with Ana
>cover Nina and Anas growing up story and how different they are. Explain why Nina is cold, calculated and antisocial while Ana is emotional, social and relies on instincts over planning.
>Grown them as characters

Then drop the surprise.... Nina is in the Game too and both of you are being paid to go after the same target (no not a Mishima related target, something crime or political). If they go solo in taking out the target, they get the others cash payout plus the remaining amount they are owed, or they could work together.
>Now the fork in the road decision, go solo Ana, solo Nina, or play as both sisters.
>Three different endings for the 3 different paths.
>Similar levels but with different solutions for how you get through, ensuring replayability.
>Different sabatoge points for if you choose to work solo where the sisters attempt to fuck over the other.

And why did I say nudity? Keep in mind this is a series where in the animated and Live action movie the Williams sisters have had 3somes togther for the right price.
So having it in the game where Nina is so calculated and detached from feelings she'd share a cock with her sister for a job, and Ana is so petty, competitive, and emotional she would try and best her sister at even sex.... that would make for a hell of a story line
