So far, every article I've seen about Baldur's Gate 3's effect on the gaming industry has been horse shit. Other studios and publishers are not "panicking," they're not going to rethink microtransactions, and they're not going to be daunted by this release; some devs have said as much already along the lines of "Yeah don't expect this breadth and scope from us going forward, because it doesn't work for our games."
This game is not the industry-spanning "gotcha" these writers have been trying to make it out to be. AAA devs or publishers are going to continue their nonsense because people will continue to buy their shit anyway, and they know it.
All that said, BG3 is the best game I've played in a number of years and hands-down the best cRPG I've ever played. It smokes Divinity, Icewind Dale, the previous BG games, NWN, etc. So if any studios do happen to have a positive takeaway from this, maybe we'll see at least some of that polish in games down the line.
