A friend and I spent 6 years making a simulation game, finally released▲1,157
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:…

I'm open-sourcing my game engine▲318
Modd.io is a collaborative game editor that runs in browser. It's kind of like Figma for game dev. We made this engine low-code and multiplayer-first, so developeres can quickly prototype casual multiplayer games. I hope some of you guys will find this useful. Would love to hear feedback also. Thank you. Engine Demo: https://www.modd.io

A Visual No-Code Game Engine – 50x Easier Than Unity▲10
I've spent 30 years making games as both a hobby and profession, working with Unity, Unreal, GameMaker, RPG Maker, Ren'Py, Godot, and many others. A few years ago, I attended a game dev meetup and met dozens of people with incredible passion for making games – but they were struggling because they lacked technical knowledge. That's when I decided to build a tool that anyone could use to create games. I started developing this as a side project, eventually raised ~$100K through crowdfunding in Korea, then secured ~$200K in angel investment. I assembled a team, and we've been building this…
