Leaving Rust gamedev after 3 years

But ultimately I sense the subtext here is much the same as with other Rust problems: the object oriented baby has been thrown out with the bathwater, often in the name of premature optimisation, but also with a sense of misplaced religious purity regarding the evils of state and the merits of functional programming. There never was any OOP law that your inheritance hierarchy had to be insane, or that you had to create classes for absolutely every last thing. Now we have people hitting the opposite extreme where everything has to go through the same function switched on a pattern matched enum. One of the core problems with Rust is it lacks the mechanisms to allow moving adequately out of this tarpit.

I still think Rust might have a place at the lowest level core where it is all about shuffling arrays of things through compute units, but for the higher level pieces it is clearly the wrong thing to be using.

1. I am using technology in order to build this thing.

2. I am building this thing in order to use this technology.

Developers often fall in the (2) camp but don't admit it. There's an allure to using the new, sexy tech that will solve all their problems, whether that's Rust, Kubernetes, LLMs, etc.

If you're in the (1) camp, you should stick with what you know; and if you know that what you know isn't enough to build the thing, you should use whatever is most common and straightforward, not something off the beaten path.

Games seem to be the biggest trap, because solo devs often end up building a game engine when they set out to build a game. If you really want to build a game, just use Unity/Unreal/Godot, I promise it'll go better for you.

It's honestly somewhat baffling to me that folks will choose Rust for gamedev right now. The state of the open sourced tools are just not there yet, especially when compared to Godot, and at the same time these games are running on PC hardware which tends to get faster every year.

Also for ECS... one thing I tended to realize is that when developing a game, pigeonholing everything into an ECS can seriously tend to get in the way. A lot of (efficiently written) game code is best handled in an infrequent event-driven way.

An ECS backed game engine like Bevy can make big mobs more efficient, but few games will actually leverage this effectively for fun gameplay and at the same time modern PCs are fast as hell.

I think about Starcraft from 1998, created when virtually all PCs only had one core, and its 200 unit per faction cap. Blizzard hasn't increased this cap because it doesn't necessarily make the game more fun. Now should a gamedev today, 26 years later, making a 2d isometric game for the PC be worried about performant multithreading????
