Valve only wants to make new Half-Life games if they push the medium forward, but what could it push

When asked to explain why Valve never made Half-Life 2: Episode 3 for the recent 20th anniversary documentary, that he "couldn't figure out why doing Episode 3 was pushing anything forward."

For the Valve founder, the Half-Life games can't just push Gordon Freeman's story forward. They have to push videogames forward in one way or another. So, if Half-Life 3 ever happens (or Episode 3, but that ship has probably sailed), what would it 'push forward'?

It's a question that hasn't gotten easier to answer in the time since Valve cancelled Episode 3.

The original Half-Life changed the way stories were told in games, expanding on potential for narrative FPSes only hinted at by Unreal, and was nigh inarguably the of its kind in its day. And then Valve somehow did it again with Half-Life 2, breaking new ground for the narrative FPS with its novel physics and top-shelf dramatic storytelling.

Finally, although it wasn't the big numbered entry people might have hoped for, Half-Life: Alyx was yet another that helped prove the potential of VR.

Assuming that 'VR again, but even better' isn't the plan for whatever the next Half-Life thing is (although that Valve's got an all-in-one headset coming), there are a few possibilities for where Valve's attention lies, at least in terms of technological innovation.

Over a decade ago, Valve in games, an idea that still mostly appears in toyish novelties today, though it's . The most striking example from Valve was a demo of Portal 2 using the player's eyes to control in-game perspective, but it also [[link]] tried a version of Left 4 Dead 2 where stress levels were monitored to dynamically change encounters. It might be old tech, but so is VR, which has had an incredibly [[link]] long and slow journey toward mainstream appeal.

And then there are the more controversial candidates. Generative AI is a big topic these days, and while its applications in gaming so far have primarily been in the form of , there have been some discussions about how AI might be used to in a thoughtful, temperate way.

There have also been efforts to incorporate generative AI directly into games, such as with , but Valve would have to make huge creative and technical leaps to get that kind of thing out of tech demos and into a game in a way that is actually good, especially in a series known for telling coherent(ish) narratives. Despite the breathless claims of the AI industry, we don't even know if such a thing is possible, even if Valve did secretly have some brilliant machine learning department.

AI still feels too experimental to be the thing Valve is fixated on, although it seems reasonable to guess that the developer could be working on something related to procedural generation that isn't necessarily tied to LLMs or machine learning.

Blockchain trading is the other controversial recent tech development, and Valve doesn't allow it in Steam games—it's got its own Steam Marketplace, after all—so it's an extremely unlikely candidate for Valve's interests.

One clue might be in Valve's recent hardware innovations: the Steam Deck and the Steam Link. Game streaming and handheld gaming certainly seem like they're here to stay when compared to some other big trends, although it's hard to imagine how they might inform the design of a new Half-Life in a way that pushes things forward—handhelds have been around a long time. Although, if Nintendo can sell me on the potential of Joy-Cons after motion controls were so finicky for so long, maybe Valve can make magic happen with something only the Steam Deck's trackpads and paddles can enable.

I think novel control inputs are always worth exploring, whether we're talking about a bespoke arcade cabinet or the Playdate's , and my intuition tells me there [[link]] has to be something that's only possible with a dual-trackpad-with-paddles setup. Or come to think of it, maybe what Half-Life 3 really needs is a crank.

It's possible that Valve is thinking about 'pushing things forward' in some way that doesn't primarily have to do with technology—design, storytelling, structure—although tech has always been a big component of Half-Life games. Half-Life 2's physics puzzles and characters who actually looked something like human beings aren't such a big deal now, but they were in 2004.

Even if Half-Life 3 never happens, the first two will always be among the and evocative games ever created, so it's hard to feel underserved. Let's just hope they get crank support soon.
