Huh, I'm pretty torn with this update, which doesn't occur often.
I tried this game ages ago and like the way it leaned more into the humorous side and you had ways to not actually be an asshole most of the time. Stayed for the story, but eventually started liking Shego, so I stuck for her content.
I was trying to avoid abusing her as much as possible, and chose not to go down the "property, slave" route, now the story is forcing those parts heavily, but it does acknowledge it, so I hope in the future we can step it down a bit. "I am your master, you belong to me", and all that jazz is an intermediate turn off for me, so I'm not enjoying this version of Senior, especially after trying to avoid it the whole game.
In addition, I have to say I'm very pleased with the writing this time because I find myself absolutely hating the new Shego. And I mean literally in the physical gag reaction hating. She went from cool and hot, to blergh, but again the story acknowledges that and even says there will be content with the evil Shego, so I am actually interested in the further story development.
