Posting before reading because activity. Godot Engine, hands down. I used Unity for years and years and now that Godot 4.x is out, I’ll probably never use Unity again. Unless it’s for a job or something like that. All personal projects tho… I could probably make a game in Godot while waiting for Unity to start up.
My vote was for Godot but this one is a very close second. I even have it installed on my mobile Firefox instance.
