I've seen some interests in (simulation) video games here on HN so I thought I'd share a short version of our story. More than 6 years ago, me and my friend from university were playing around with an idea of making a game we always wanted to play. We worked on it on weekends but the progress was quite slow, especially due to so many dead ends and wasted effort. Eventually however, we solidified our direction and decided to take the risk to resign from our well paid SWE jobs and work on it full time. It took more than a year but yesterday we have finally released it on Steam:…

Hello guys, I'm glad to present to you PlayAlgoShip, a web-based game where you solve fun algorithmic puzzles. The rules are simple, you need to find the correct algorithm that makes the ship collect all stars. If you succeed, you will unlock the next level! There are also live statistics like how many players are currently playing on your current level (you are not alone struggling!), the finish rate of the level, and how many players liked/disliked it. It's 100% free, I hope you will enjoy the experience!

I built this with Claude cause I always wanted to tinker with a simulation economoy and I love space themes. A space-economy sim where nothing is scripted. A few hundred autonomous ships each run their own planner. Some chase the best trade route, take a delivery contract, refuel, retrofit at a shipyard, or dock so the crew can rest before morale tanks. Markets price everything off supply with shortage-urgency multipliers, factions tax and subsidize, populations migrate when they're unhappy, and stations that go broke get abandoned and rot. It started as an Elixir/Phoenix prototype, but…

I didn't realize Universe Sandbox ran on MacOS, and I was in the mood to play around a bit. Some functions it's got: - Random system generation - Sonification is super fun too - Habitability Simulation (Just for fun, don't cite this please) - Replacing, spawning, deleting objects I've had tons of fun building this, so I hope someone else can share the joy. It's free and runs in the browser. I'd love to hear any feedback. I think this is at a state where I might leave it as it is, but if people are interested in other features, maybe I'll keep working on it. I've kept saying I'll stop working…

Hi HN! I'm working on an open-world multiplayer space sim with submarine-warfare-inspired combat. Crew a ship, haul cargo, run heists, hunt your foes with passive and active sensors. Browser-based, free, no install. Some of its features: - Submarine-style passive sensors. Contacts start as a bearing line (direction, no distance), resolve into an uncertainty circle, then into a full track. You triangulate over time by moving. - Silent running. Cut your emissions and witnesses can't ID you. - Newtonian flight. No drag, no auto-brake. Flip 180° and burn to stop. - Boarding combat. Dock with…

After losing my job, I decided to channel my energy into creating my own sci-fi adventure game. While I’ve previously released a VR game, I’ve been working as a regular software developer for the past few years. The game, Star Mission: Remote Sectors, is a first-person exploration and survival experience set on an uncharted alien planet. Players use superhuman abilities like telekinesis to uncover anomalies, navigate environmental hazards, and survive in hostile conditions. A big inspiration for the game was classic sci-fi movies and the optimistic vision of Star Trek. The journey has been…

I built a realistic prod system under heavy pressure where you SSH in and solve real problems. You get your own server (real box) and have to fix various things up under fire. a friend told me it reminded them of DOOM for SREs, another called it a "flight simulator" because you can do anything (and reboot if you crash). someone else said it was like "an escape room for engineers", in that you have to find your own way around an unfamiliar box and solve puzzles. idk, maybe it's fun. try it! how it works: you get two Hetzner servers: a traffic generator (real traffic from NYC taxi data highly…

I made a lightweight web game about compute CAPEX tradeoffs: https://darios-dilemma.up.railway.app/ No signup, runs on mobile/desktop. Loop per round: 1. choose compute capacity 2. forecast demand 3. allocate capacity between training and inference 4. random demand shock resolves outcome You can end profitable, cash constrained, or bankrupt depending on allocation + forecast error. Goal was to make the decision surface intuitive in 2–3 minutes per run. It’s a toy model and deliberately omits many real world factors. Note: this is based on what I learned after listening to…

Hi all! I've been doing spacecraft system engineering since grad school and got to keep doing it after school at Care Weather. I tried several approaches for keeping hundreds of napkin math equations and connected simulations up-to-date, but none of them were both reliable and easy to use. To solve that, I made Oneil, a design specification language with clean syntax for specifying and evaluating math describing a complex system. Oneil has been really helpful as we design one satellite iteration after another for ground testing and spaceflight. I'm really interested in hearing feedback and…
