Reject modernity, return to offline gaming. The ps2 is right there, and the gamecube, and the xbox. RIGHT. THERE. And sega and atari and older nintendo systems. They even have some new games for older systems. People are making new games for these things, probably breaking some sort of shitty ip law, but who gives a fuck, these things have not outlived their usefulness, asshole companies have just abandoned them. For example you could put out a 2023 trivia game on an NES, or even an Atari. You could put out seasonal games with simple adventures and stories. Like childrens books but freshly minted carts. And kids playing an NES don't have access to the internet since it's just a fucking NES.
@Jazzy_Butts maybe if a game doesn't need to have online connection, just nix it with your firewall
