Yes I have used a few different engines, both free and licenced, and I have found Godot is best for me and I can do anything I need to in it. 

Yes, atmosphere is one of the things I try to focus more on because it helps players enjoy the game more because it's more immersive. Even in like pixel art or low poly 2d and 3d games, just adding a bit more atmosphere like lighting, sound, and particles makes it feel more alive and enjoyable.

As long as you choose an engine that you understand and learn it, you'll probably enjoy making games. Just don't use too many different engines and stuff, fo us on one or maybe two so you can get better at what you want to do
