Aspyr! I was a Mac user in an era that was 95% Windows, and Aspyr brought quality games over to our side of the pond. I remember they ported Alpha Centauri in particular, but there were lots of other ones too.
Also Bungie back in that era—they were Mac-exclusive and putting out the amazing Marathon series. I was heartbroken when I saw the trailer for the new “Marathon” game that looks nothing like the originals.
This is probably not a terribly helpful answer, but on the iOS side, there is Apple Arcade, which is a huge library of “free” (aka included with the subscription) games that don’t have any ads or microtransactions. If there’s an Android equivalent, just give her that as her app store. You’d spend a set amount per month and keep her away from the predatory business models.
As someone who has lived in three different boroughs in NYC, I am so thrilled by this. I loved the NYC of the first one but didn’t like that it was just Manhattan, when comics Spider-Man lives in Queens and sometimes goes to Brooklyn. Great decision to expand it.
