Wait, what? That's way more interesting than what I thought the last time I played. I figured the guy getting bullied was the NTS character you could share with out of pity and the guy doing the bullying was the NTR character you had to either compete with or just opt out of. Any more you'd be willing to share on that matter?
Anti-cheat...not that anyone asked, but consider the purpose of these games. It's to have fun, right? To give your audience a positive experience. You hope that they'll enjoy the art, writing, gameplay, or sex scenes--if not some combination of the four. I had a blast with the early, imbalanced versions of Tamer Vale--for whatever reason, coming up with unreasonably OP builds was more gratifying than the porn.
Is it better to play games "optimally," "as the devs intended," or "however you have the most fun?"
You do you, but I think anti-cheat is wasted effort. There's always going to be people who cheat. Some of them literally just want to see how the game handles being fucked with. It's better, and probably more satisfying, to just try to make the game fun to play. Spicing up the grind with content that isn't in the gallery is one method. You could also try easter eggs that show up rarely or irregularly, or give people settings that let them adjust how much grinding they actually do.
