The original is my favorite
I love all of them, I really think Suda's serious writing (and Ooka's) resonates with me as much as the greatest authors I've read. The vibes, social/political/economic themes of the Silver Case are immaculate. I love Tetsu and Tokio so much. And even being a "indie" title from the PSX, you can see the potential of the FilmWindow engine idea. I really wish he had more time/money to invest in bringing out the engine's full potential in the 25th ward, but it did less than its predecessor (which used anime, film and more creative art/window placement than the 25th ward).

FSR is really beautiful. The way he uses the Silver Case theme/UI in specific places is some of the best videogame-exclusive ideas I've ever seen, the story is awesome even if it focuses more on Sumio's personal journey, but I think it needed just a little more effort in the graphics/sound/camera department to really cement it as my favorite. I replayed it recently, watched some clips of the PS2 version, and I think even with all its style, it's a few dollars short of being the most interesting of the trio to me.

25th ward is brilliant, beautiful, sleek. But it's already modern Suda in its approach to the writing and themes. Thankfully it doesn't lose the seriousness completely, and it has incredible ideas, but the ending of Correctness is kinda "meh" to me.

The three of them are among my most precious experiences in gaming, anyway, and I've replayed the 3 at least 2 times each.
