I'm always advocating for multiple paths in a game's storyline. I know it's hard to do, so I don't really have high hopes for such a feature to be more prevalent. But on the other hand, you get a JRPG like Shin Megami Tensei where some of their endgame content does contain multiple paths depending on whom you side with (SMT IV comes to mind). I believe Fire Emblem games also contain different paths based on whom you side with. I feel like this is mostly a JRPG thing though, because whenever a western RPG does it, they'd often resort to the lazy "slideshow" method like Fallout: New Vegas or Mass Effect 3, instead of creating three distinctly different gameplay levels based on player choices.
Now, obviously, games like Detroit: Become Human and The Dark Picture anthology could do it easily because they lack gameplay features outside of QTE, so it's easy to make them. But I would propose for game developers to be more daring and innovative, creating full game levels with multiple paths. You see this in older RPGs too like Dragon Age: Origins, so I don't know more AAA games these days don't have such features anymore. I heard The Witcher 3 had multiple paths, but I'm not really a fan of medieval fantasy settings, which is why when CD Projekt Red announced Cyberpunk: 2077, I thought we were going to get Witcher 3 with a sci-fi cyberpunk setting, with all the multiple paths Witcher 3 had to offer. Alas, that was not so, with the way the life paths were described by people who've played them.
Another cool concept I've really liked in the past is Undertale with the players' act of pacifism being a core important part of the story, and even though I had my problems with the message, Spec Ops: The Line had a nice concept like that as well, so I wouldn't mind seeing more games in the future turn the game genre on itself, like the Goombas in a Mario game calling out Mario for stomping on them all the time or something, or a Pokémon game where the questionable ethics of dog-fighting comes into question. Just spice things up a little and do a little subversion to make the familiar formula fresher, more interesting.
BioShock had a good idea in terms of farming the Little Sisters for ADAM, but they made it too easy morally to choose not to farm them. And I'm not talking about how challenging the gameplay is, but rather, making the decision more morally grey. I'm not exactly sure how to do it, especially in the obviously morally questionable objectivism of BioShock context, but a game where the innocence of a malicious ghost child comes into question would be interesting as well in horror games. Imagine having to play through Silent Hill 2 without killing any monsters, for example.
Speaking of horror games, here's a concept for you: a protagonist whose appearance becomes more grotesque depending on your moral actions, but the other characters actually call out on this. In most games that have such a feature, I feel like the NPCs don't usually call out on the protagonist's appearance, such as Mass Effect or even Fable.
How about a horror protagonist with some kind of disease that gradually makes them become as deformed as the monsters they fight? Maybe the deformed lump of flesh becomes a burden even that movement becomes harder by the end of the game, and maybe depending on your choices, you could either become one of the monsters or fight against the disease with all your might.
I don't know. I'm just spitballing here. 😛 Hope it helps. lol
