There was a lot of panic about “killer games” in the 90s-00s. Politicians and parents blamed video games for school shootings. Nowadays nobody cares about the topic at all, but the strict rules remain. Steam just kind of ignored the local laws so far, but now decided to actually adhere to them.
I have a perfectly capable gaming PC but more often than not, I choose to play on the Steam Deck instead. I already sit at my desk for work most of the day, so it’s nice having a dedicated gaming device that I can take with me and sit in the garden or on my sofa. And of course I can take it with me when travelling.
