The Total Beginner's Guide to Game AI

My biggest complaint about Rimworld, and in fact most games, is the lack of causality in random events. This is caused by developers giving up on this complexity in favor of just rolling dice. Just because it's hard to provide a UI that can express these things doesn't make for a satisfying experience by completely ditching the sense that events have causes. When an event has a cause, it gives the player a feeling of agency, and when it's just a roll of the dice that you can make go away by reloading the save file from a few seconds before, they're no longer disasters, but just random bullshit the game throws at you for the sake of making things hard. It feels cheap and lame.

If you get raided, you should be able to scout the caravan before it arrives. If bugs tunnel under your base, your ground penetrating scanner should detect them in time to get in position to defend. The list goes on, and the solutions to the UX challenges are there, if developers didn't simply throw their hands up and say "Welp, that's just too much UX for me!"

The game that got randomness right was Diplomacy. There's no dice rolling at all, but the randomness is there because you don't know what 6 other people are going to do when you put in your orders, but you rely on them holding to their agreements for the success of your own moves. It's a very satisfying mechanic because randomness is still causal. Randomness truly represents your lack of information, and can be mitigated by your ability to extract reliable information from the other players. When you get screwed by randomness, it doesn't feel like arbitrary bullshit. Knowing that effects have causes is crucial for people's ability to form a narrative about their experience.

What isn't necessary is to simulate reality down to the smallest detail, which is what I feel like most people try to do when they end up complaining that it's too complex to present to the user and has minimal effect on gameplay. One needs to be smart about simulating the things that do have an effect on gameplay by focussing on narrative mechanics, and not just trying to recreate physics.

In short, the solution to complexity is not getting rid of it and replacing it with unsatisfying random chance, but instead to create a renormalized model that eliminates the extraneous degrees of freedom.

Thanks! I will check it out. I tried Rimworld but after playing it for 20+ hours I began to see the patterns and non-randomness of the game (I have been heavily biased by DF). Plus everything the other in response. Im gonna check out your blog when I get the chance (currently on vacation).

I have just (just!) started making a DF like game but will be based off the D&D world. I am starting from the bottom because I want the challenge and have less priority on completing the game (and more on learning/challenging myself). When I mean bottom, I have almost finished creating a path finding algorithm that should be much faster than the current ones out there (geared towards 3D grids like DF). I also created a line of site algorithm that is symmetrical and (so far in testing) angle/corner perfect. World generation will be based on tectonic plate movement (bare bones version created).
