"I added the Silver Case games to my Steam wishlist, I hope there is a way to get physical copies for them on consoles!"
Right you are, my friend! The Silver Case and The 25th Ward remasters are both available on Switch physically. You can get them in the Silver Case 2425 physical copy, you can usually find those on Amazon. I myself bought the deluxe edition with the artbook and soundtrack, but I can't say I recommend it. The artbook/soundtrack you get with that is pitiful compared to what you get on Steam. (You get about half of the Steam artbook and a total of 10 songs between the two games for the Silver 2425 deluxe edition)

Ah shit you want me to rank my favorites? That's like asking a parent to pick a favorite child!
Well, of the 7 I played, I think this would have to be my ranking of my enjoyment of the games:
1. The 25th Ward
2. Killer7
3. No More Heroes
4. The Silver Case
5. No More Heroes 3
6. No More Heroes 2
7. Flower, Sun, and Rain
I will say that this is based off of my overall enjoyment, if this was more objective, then No More Heroes would find its way to Number 1 for being the most accessible and simple to understand Suda game.
None-the-less if you have a bit... a LOT of patience and an appreciation for cool convoluted and crazy stories you'll probably enjoy some of the stranger games.

Hey, it's been a minute since I touched base.
How's the Kill the Past journey going? You finish Killer7 or any of the other games yet?
I myself just finished The 25th Ward and I gotta say it's my favorite of the series so far, it beat out even No More Heroes and Killer7, which is no small feat!

Yeah they should be part of the story where the NPCs are confused about how they look and where they come from. Then again they didn't seem to have much of a reaction to your Arc phone though lol.
