IANAL but yea probably? Same as any cloud server.

I’m not sure of an AGPL game or technology would ever be knowingly used inside a cloud service

Yes, always.

(If you want a more nuanced answer, we need a more nuanced question. I general, the AGPL is applicable in cloud-gaming as well as bakeries and at high altutide. I hope you play fair by making source of your AGPL-code-enabled backends available to gamers!)

Thanks, next time I'll make a more nuanced question, promise. I'm building open source games, not a cloud gaming platform. So I was just curious if the AGPL covers also cloud gaming, since I didn't really find something on the web to that specific topic.
