For games, a big one is that none of the common APIs are supported, apple just supports Metal and nothing else. There are compatibility layers, but it's a hurdle.
That looks like an interesting project, but it seems it hasn't been updated in over a year, and is only compatible with bevy 0.6. The current version is 0.11 or something. I've had my ass kicked before by relying on projects that didn't have a lot of support available, so I would stay out of this one.
Thanks. We're fortunately still on 2022, so it won't really affect us at this point.
I've been keeping an eye on godot for a while, it seems like a very interesting engine. I'm not sure if it's ready for prime time for the scale and rendering quality we're usually looking for, but it might be a great option for 2D and smaller-scale projects.
Unity dev here. Will switch on our next game, but don't have the choice for the current game that we've already invested 4 years into.
Also, bevy looks nice code-wise but it desparately needs a proper editor and GUI to make it artist friendly
