I wonder how much sense that would actually make for them. All the major console makers subsidize their products through game sales and online subscriptions. Valve already does the former, but that’s because they’re a game marketplace and it’s how they make money to begin with. I’m not sure what a steam subscription service (that’s not a game pass) would look like, since Microsoft, Sony, and Nintendo offer online play and cloud saves for the cost of a subscription, whereas Valve makes those available for free.
There’s a decent chance you might not be missing anything, it’s just not for you. Minecraft and Terraria are beloved titles that people put thousands of hours into, but I never got into them myself.
A turn-based CRPG is a very old-fashioned thing (the C stands for Computer), and it’s a pretty faithful adaption of a TT (tabletop, so pen-and-paper) RPG, which is even older (though the current ruleset for DnD is pretty new). I can definitely understand how Skyrim appeals to you but something like BG3 doesn’t; they’re fundamentally different games, and Skyrim is much faster-paced
