I'm using arcade for the first time. It's a python library that (I learned after starting) seems to be aimed mainly at classroom environments. I heard it highly recommended somewhere, but so far I'm not as impressed as I hoped to be. I've had to read the source a lot where the docs are lacking, but the source is very readable. It also makes a bunch of choices under the assumption that you are developing a real-time game with moving and colliding sprites, which I'm not.
It was a lot simpler to install and get working than pygame, though.
