Creator's Pet: Oswald in the first game. He has the longest path, the most choices, and on top of everything, he's the canon love interest. This also counts for Cain and Thanos; as noted on the character page, Cain is the only love interest Oswald approves of. The character type itself seems to be a thing for the writer.
Narm Charm: The first game features the majority of grammatical errors, which can make it dip into So Bad, It's Good territory at times.
One sterling example can be seen in the second game, where Thanos is trying to convince Valen that their world runs on Grey and Gray Morality. Aside from the fact that the setting is far sweeter and safer than the games try to insist, the whole thing becomes kind of goofy with this gem of a line: "Do you think you haven't hurted anyone?"
