I’m replaying Bug Fables, which is a kind of spiritual successor to the first two Paper Mario games. Definitely can recommend if you like that style of game!

This is cool and all, but Wi-Fi and Li-Fi are equally “light-based”, it’s just using different frequencies. A higher frequency means potentially faster data transmission, but at the cost of faster attenuation. We see this with 2.4GHz vs 5GHz wifi already, and this sounds to me like a more extreme version of that
