I wanted to counter some of the child comments who say that it's a bit of a child engine with some real world results. After all, people are making great games today with Pico-8 or on a Game Boy, surely there must be some great indie Pygame games. Now, these aren't AAA developers, but it seems to have as much capability as something like Love2D does.
Sure enough, there's quite a few = https://itch.io/games/made-with-pygame
(Side note, when I first searched for the 'pygame' tag on Itch, I got nothing. It didn't even suggest it as a tag, wouldn't let me search for it. However Googling "games made with pygame" provided the Itch tag as the first result, not sure why that was)
