They’ve reset mine twice before many years ago. I’m sure Minecraft is my top overall. In steam it says Metal Gear Solid 5 is my top but I would leave it running sometimes for the research to finish. Second is Garry’s Mod. I played that A LOT when I was younger.
It’s not always so simple. I’m in Fintech so have to take the UDAAP course every year or so and the law is more consumer friendly than you’d expect, at least for the US. The deceptive bit is probably the most relevant. If the person signing them up for it told them “you won’t be charged” but failed to mention that they would be charged later that is an example of a deceptive practice.
