If you want to guarantee a load of haters, just make a fan game with Cindy from 'Our Red String' as the MC. She's loved and loathed in equal measure. And then of course, you have all those fanatical supporters who view you as ripping off Eva. Unless she states unequivocally that you're not, all those people will believe that you are, and they'll hate you with a passion, for daring to profit from Eva's masterpiece.
Whenever, I make any comment about Cindy, on the 'Our Red String' thread, I'm amazed how many people appear to completely hate her, as if she was the Devil Incarnate. So maybe it's a bit of a risk making her the MC of this game? Because whatever direction you take her in as a character, many people are already predisposed to dislike her intensely, and will carry on disliking her and behave as if she's the cause of all ills in the world.
I mean she betrayed Wade (it wasn't his fault he thought playing games was more important than their relationship), and she led Ian on (she was just too hot for Ian to not pursue her like a complete stalker, and encourage his best friend Wade, to say all the things guaranteed to split him and Cindy up), and she clearly lusted after Axel and pursued him till he gave into her charms(who never did everything he could to manipulate Cindy's naivety and desire for a guy who actually seemed to be paying attention to her).
It's clear some players, actually believe these things. That she's some kind of evil femme fatale, that men are incapable of resisting, and her ex boyfriend Wade is a victim of her wicked designs, and never did anything to make Cindy think she'd be better off elsewhere.
So if this game has her going down a corruption path, you can already imagine her detractors saying, 'We always knew she was a whore, she was probably whoring away behind Wade's back long before Axel or Ian came on the scene', and it will simply confirm their belief that Cindy is actually doing that right now, off camera, in 'Our Red String' as well.
