One of my dream games is a truly open world text adventure. I got a glimpse of it by having ChatGPT run this game, but it started hallucinating and misremembering after a few rounds. It has to be perfect to avoid breaking the immersion, but I'd pay $100 for such a game even without graphics.
Isn't this what MUDs are? I tried a few in the early days of the internet and even back then they were like much bigger and more dynamic versions of text adventures of the 80s. For me I bounced off the idea that I had to role-play with other humans - I thought it was far more interesting to chat with other humans about real-world topics - but if you are looking for a large, text-based role-play experience then it's probably worth trying out a few. There might even be some that can be soloed these days, there are so many.
I think the challenge of trying to make an "endless" game using an LLM is the same challenge that all procgen games face - they are boring for people who are seeking a well-paced narrative. There are players who enjoy the mechanics of looting/crafting/trading/etc who will gladly play games where the story is incidental or emergent, but if you're specifically looking for something with a bit more narrative depth, I'm not sure procgen will ever work. Even if there is a system that tries to project coherent storylines onto the generated world, you still need the player to do things that fit into a storyline (and not break the world in such a way that it undermines the storyline!), otherwise the pacing will be off. But if the system forces the player into a storyline, then it breaks the illusion that the world was ever truly open. So you can't have it both ways - either there is a narrative arc that the player submits to, or the player is building their own narrative inside a sandbox.
AAA games try to have it both ways, of course, but it's always pretty clear when you are walking through procgen locations and leafing through stacks of irrelevant lore vs when you are playing a bespoke storyline mission that meaningfully progresses the state of the world.
What I wanted in MUDs was a simple editor to allow people with little technical skill a means to create a world—or extend an existing one. And then I wanted a way to join MUDs together—like if you leave a forest by a certain path you are, unbeknownst to you, rerouted to a different MUD that picks up where the forest left off.
In this way I imagined in time a world larger and richer than any that had come before it—where you could really just keep going, keep playing, never see all of it.
I never got deep into it, but I remember reading magazine articles back in the 90s that that's exactly what the new generation of MUDs were. Wiki has pages on MOO, TinyMUCK, MUSH etc - these are basically platforms where the players themselves can expand out new objects and locations, presumably in a similar way to Second Life or other MMO sandboxes do today.
So the tools already exist, but it seems to me that they primarily appeal to a very specific type of gamer, one that doesn't have much overlap with the type of gamer who would like an "endless" open world or the type of gamer who would like a tightly-plotted narrative experience. I think it's more something that appeals to fans of table-top RPGs, people who are looking for a collaborative storytelling environment.
I think many gamers have the imagination of an epic infinite metaverse style game, but then when they actually get the opportunity to participate in one, it turns out that that's not really what they wanted after all, because it requires a level of creative labor that they weren't expecting. This is why I think the market has naturally segmented into sandbox builders, survival/roguelikes, traditional narrative adventures etc.
My experience was that in practice all that mapped-out world of most social mu*s was largely ignored by players; they'd all end up in a few gathering spots, or in private spaces disconnected from the main map, open only to their owners and people they teleported in.
MUDs are a low-tech version of what I'm describing. It relies on other people being available and generally leverages the usual tropes with repetitive killing-based gameplay.
LLMs are limited today, but one day they may be able to provide the well-paced narrative you're talking about. The LLM would be a skilled fiction writer that would introduce interesting events as I explore the world.
If I decide to go to a bar and talk to random strangers, it could give me interesting life stories to listen without any action. But, suddenly, a mysterious man walks in, gives me a sealed envelope and departs without saying a word... What is in the envelope?
You can do this with regard to a MUD too, but typically out of character
and not every MUD would allow OOC chatting within the game world, as that
is disruptive to those players who seek immersion.
It seems to me as if you may not have found a good roleplaying MUD back when
you played MUDs. You may be missing out on that experience. I retired from
playing MUDs about 11 years ago permanently, but the in-world roleplay was
the only thing that was interesting to me since it was the creation of a
unique storyline potentially involving many other playercharacters.
I think I just don't really vibe with roleplaying in realtime with other humans, to be honest. I grew up trying to play tabletop RPGs (my dad was a DM and used D&D mechanics as a way to make storytime more engaging), but while I really enjoyed making up characters, I never had much fun actually doing a campaign.
The thing I love about computer games is that I can go through them at my own pace, pause whenever I like, hang around looking at a cool visual, go back to an old save and try something different, whatever. Multiplayer takes all that freedom away because everything has to progress on somebody else's timetable, which isn't as fun for me. Nowadays being expected to perform on a time limit just reminds me of work, which is the last thing I want when I'm playing a game.
It is my understanding that muds (and all the flavors of Mush in particular) can sort-of do it, by letting players create their own story through roleplay, supported by an extremely open (and often player-modifiable) world, as well as good admins / GMs.
That is more like "computer tabletop", however, and doesn't scale beyond a small number of players.
You're on to something. I tried this too, a few months ago, with offline Ollama/Magistral on Mac. "You're a dungeonmaster for a single player adventure game, with me as the player..."
It lost track of things almost immediately. But the foundation was there.
Maybe if we had a MUD-tuned model...
If it has an approximate way to track state, and a "pre-caching" method where it can internally generate an entire town all at once, room by room, so hallucinations are rarer... actually starts to sound like a traditional DM's method of world building for a campaign.
I've never played Avalon but it looks like a better text adventure. I'm not talking about hardcoded or randomized worlds, but truly reactive worlds.
In my experiment with ChatGPT, I was walking around in a museum (that was the scenario) and decided to flirt with a woman who happened to be there. The flirting was something I decided to do on the spot with no prompting from the AI. The woman had just been part of the room description up to that point. But it reacted to this new situation in a semi-realistic way, essentially creating a new "adventure" on the spot. I met her on the next day, brought a gift (and so did she), but then it started hallucinating... :(
It did for a long time, but depending on busy friends makes it so I can't play this whenever I want. My "dream" game is a single-player game I can play as many times I want without having to rely on others.
