Pico-8 is a pretty fun little environment. The limitations work to its benefit, because it's fun to see what people can squeeze out of it, and you get a lot of weird and cool and unique stuff that I'm not sure would exist with our infinitely powerful computers today.
I have a rg35xx to run some old emulators on, but it came with Pico-8 and a few games installed - these are some of the games I enjoy the most. The look great in the screen/size and I really need to seek out some more to install.
