To summarize, the EU Kids Act is considering video games a service, therefore the following restrictions will apply:
- ID Requirement for gaming.
- Indie games that cannot verify your age will thus not be legal within the EU.
Applies to all games retroactively.
If you're 18+ in the EU you should consider signing the "Stop killing the Internet" citizens' initiative https://eci.ec.europa.eu/066/public/#/screen/home
