Well, I think one needs morals to find someone being a serial killer a bad thing, and luckily I am free from those. ^_^
My biggest problem with most games is that people advertised as villains tends to be anti-heroes in disguise.
OR there is zero happy endings with them. (Locked up is -not- happy. Unless you choose to be. I'm big on Free Will, but ironically enough I adore manipulation. I dislike brute force tho, and tend to view that as a sign of stupidity. If you can't make people -want- to have you, you're clearly not doing a good job. Kidnapping is best left as a last resort when all other methods have failed.)
(I may use the word 'happy ending' a bit loosely here. Happy in my world does not always match happy in the world of other people.
My favorite character at this point (aside from Sebastian Dallarosa) is Sol from The Kid in the Back. (He's also my view on hot looks.)
The fact that he slips you sleeping-pills so he can sleep next to you it utterly charming. And I suppose I wouldn't have minded a bit more NSFW content over it either. Which says something about what I like I think. lol)
Yandere games tend to be better than other type games tho.
But it varies a lot from game to game.
The game premise is very good tho, and I can't predict the writing without trying to play it, but the art is kinda horrid.
(But a part of that is the muscles. NOT a fan of beefcakes. *shudders* )
