It's interesting how much faster he got tired of writing Lupin stories than Arthur Conan Doyle got tired of Sherlock.

The ending is kind of tasteless, because it's Leblanc trying to get rid of Lupin again as a character, but he does so in a way that allows him to fall back on Lupin if he ever needs money, unlike last time he tried to get rid of the character.

It's just interesting simply because you would expect him to be at home everywhere, but no, loyalty to France in his personal code is as important as not killing.

Near the end when Lupin talks with the Kaiser, he says he has no ties anywhere any more. He is offered to lead the Kaiser's personal police force. He declines because he is French.
"This tie is unbreakable, sire. As a person I'm dead, but as a Frenchman, I'm alive!"

If you show Joker skipping on sleep because he has too much to do, you're killing the magic.
The entire reason for I liked the game was that it still seemed achievable. I could lead a good life like that, and do it effortlessly.
Don't try to tell me it's hard. Please.

Which is the exact opposite of why the game's routine is nice. There is a lot to do, but you never feel like you are weighed down by your tasks when you play. The routine is idealised and effortless.

I guess my main nitpicky criticism of it would be that the author realized that the "daily routine" was incredibly important to the feel of the game, but he then he screws it up a bit by showing the protagonist to be in a rush constantly.
