I know, clear as mud! A few summary paragraphs I plucked from it:

If you have a game, website or mobile app that involves player to player chat, or a website or mobile app (inc. web/mobile games) that includes any kind of purchasing, you need to be aware of and compliant with EAA – though micro-enterprises (small headcount, small turnover/balance) are exempt.

GPSR means it’s now illegal to target any game at the European market unless there’s an assigned safety rep with a Europe address (with contact details communicated to both players and the authorities), and the game has had a safety risk assessment which is documented in the game’s T&Cs.

GPSR applies to products placed on the EU market after 13th December 2024. For online sales, it’s about whether EU citizens are targeted. Just the fact that Eu citizens can purchase isn’t enough, targeted at them means for example being able to pay in Euros, have delivery of a physical product to an EU country, or access info in European languages.
