This is already answered in this forum post but to go into further detail, an “engine” is simply code that runs a game, so it’s impossible to create a game without an engine. If you’re using a framework or library instead, it simply means you’re creating your own game engine, however simple. So, yes.

I have now added an entry to the FAQ about this.

hey bro, I'm also using pygame to make games and I'm a beginner, do you want to team up?
