The developers explained that the upcoming Patch 3 will bring “the first changes that affect story”. So, “Unfortunately, this means Patch 3 will introduce the first save incompatibility, transitioning to the new version.” For folks who don’t want to start over every time a patch breaks combability, Larian plan to add the previous version to Steam as an opt-in fallback. That’ll be hidden in the beta branch options. You might want to disable automatic updates for the game too. On GOG, I assume you can just choose not to download the update. Stadia won’t have this option (“for the moment”, at least), so the six people playing on Google’s cloud gaming service will need to start over. While Baldur’s Gate 3 is far from finished, it is a good’un if you can’t wait. You just might be better off waiting. “If it were not for this job, and having the self-control of four year old at a birthday party (or games journalist presented with a plate of miniburgers at a press event), I would would want to see this enticing story play out in full,” Matthew Castle said in our Baldur’s Gate 3 early access review. “Don’t feel pressured to gather your party and venture forth, but based on what I’ve seen, I think that party is in for one hell of a ride when they do.”
