I wish there were more games/gamedev activity surronding the raspberry pi. The communinty surronding the activity is minimal. The only website directly related to it that I know of is https://pigame.dev/ The website is nice but it misses a lot of the native tools that the pi ships with such as Scratch, Pygame Zero, and Sonic-Pi, which is a shame.

There is a single book written on the matter called Python, PyGame, and Raspberry Pi Game Development and it's not very popular.

I hope one day that the community is more popular and in fact I may start a game jam for it on itch.io.
