It seems to me like most PC gamers don't touch mods unless there's an easy automated way to install them, something like steam workshop or maybe a mod manager if they're feeling adventurous. It's true that mods are harder to do on linux/deck right now, but I'm hoping with the rise of official mod managers that support linux it won't be any harder. Games that use steam workshop or have built in mod support (like BG3 and Deep Rock Galactic) are already just as easy to install mods on deck compared to windows.
I think the Deck is in a nice place where it streamlines the gaming experience for most people, but still gives you the option to do more advanced things if you want.
The Yakuza games alternate wildly between being extremely serious dramas about underworld crime, and extremely light hearted and wacky side quests. Some people might find the change in tone breaks immersion, but I find the two extremes increase the impact of each other. When a game is serious all the time I get numb to it, there needs to be a variety of lighthearted content for me to really feel the impact of when things get heavy.
