ECS, Finally
I've also been enjoying building My First Game™ in Bevy using ECS. The community around Bevy really shines, but Flecs (https://github.com/SanderMertens/flecs) is arguably a more mature, open-source ECS implementation. You don't get to write in Rust, though, which makes it less cool in my book :)
I'm not very proud of the code I've written because I've found writing a game to be much more confusing than building websites + backends, but, as the author notes, it certainly feels more elegant than OOP or globals given the context.
I'm building for WASM and Bevy's parallelism isn't supported in that context (yet? https://github.com/bevyengine/bevy/issues/4078), so the performance wins are just so-so. Sharing a thread with UI rendering suuucks.

Introducing Ecsact
Since we wanted a common game simulation that would be on both the server and the client we looked into a few libraries that would fit our ECS needs. It was decided we were going to write this common part of our game in C++, but rust was considered. C++ was a familiar language for us so naturally EnTT and flecs came up right away. I had used EnTT before, writing some small demo projects, so our choice was made based on familiarity. In order to integrate with Unity we created a small C interface to communicate between our simulation code and Unity’s C#. Here’s close to what it looked like. I removed some parts for brevity sake.

What are the limits of blueprints?
There's also a performance question. While we can now use Blueprint nativization to convert Blueprints to C++ the result will be a fairly naive version, fast enough for most purposes but not if you're trying to push every bit of performance. This is where you're looking at making sure you're hitting things such as using the CPU cache as well as possible for an ECS system (Look at ENTT or Flecs if you want to see what they're about and why you'd want one), or a system needing to process massive amounts of data quickly such as the Voxel Plugin.

What's the hot tech stack these days?
If I knew C++ and I'd heard about it before I started my current project, I would have been tempted to use this https://github.com/SanderMertens/flecs which can be built to WASM. Of course you still need JavaScript in the front end to link to the WASM part. I've recently been using esbuild to bundle my front end code, which does a pretty similar job to webpack, but is a bit faster.

Bevy and WebGPU
When do think bevy will support entity-entity relationships ? https://github.com/bevyengine/bevy/issues/3742.
Flecs ECS already supports this: https://github.com/SanderMertens/flecs/blob/master/docs/Rela...

any resources for expanding on ECS?
For a modern engine you’re probably best looking at Unity’s DOTS. You may also want to check out some of the different open source ECS libraries such as flecs and EnTT are two popular ones for C++, but there’s lots of them. Largely you’ll see lots of different approaches taken, all with their own pros and cons. Not all of them will be performant (some focus more on the design benefits) while others will be optimised for certain use cases. What you should prioritise will depend on your specific needs.

Can't make my mind about which engine to use
libGDX is great, but I can understand if it's not for some people. This also applies to love2d, raylib and Monogame

I want to make a game but I'm scared...
raylib (c/c++) reliable, good docs, more or less same idea as love2d plus 3d support, but more flexible, and can be used outside game development, like visualizing data. I suggest you pick this if you want to learn low level system language - c/c++

LÖVE: a framework to make 2D games in Lua
I love love2D. It's really a breath of fresh air. I've made many little games and prototypes with it. Lua is fun, and the doco is great.
If you're looking in that realm I also have to mention RayLib [1]. It might remind you of the XNA days, except it runs on many platforms and it actually works! (sic.)
Final plug is of course PICO8.[2] Very different style once again but so much fun!
