I actually think Seth MacFarlane is a solid choice for this kind of story. People only remember his comedy shows, but if you watch his sci-fi work, he can balance humor and serious moments pretty well. The concept of humans forced into a game show after an alien invasion sounds dark, but also very flexible for different tones. I like that the story includes game mechanics like leveling up, because it gives structure to the character’s progress. The part about the cat being his main companion is strange, but it might work if they write it carefully. My only concern is pacing, because there are already many books. If they rush it, the story could feel messy. If they take time, it could turn into something really interesting.
