This is really disappointing. I chose GOG over Steam as a gut reaction - while I love Steam, any DRM is obstructive, so why not go DRM-free. Had I known that this version of the game wouldn't receive the same support priority as Steam, I simply would have chosen Steam. I think I know why this wouldn't be well-communicated beforehand, but you've left me remorsefully wishing I had redeemed a different version of the game. I know in the grand scheme of things, it's not a major impact. Only 10 hours in, and I already love this game. But this still leaves me feeling disadvantaged. It's a bummer.
Any news on improving patch roll-outs in the future to all platforms simultaneously? Barring that; if Steam will always be treated preferentially, is it not unreasonable to request to transfer my purchase over to that platform? I know that's a troublesome request that's easier to dismiss than fulfill, but what's a fair option, here?
The problem is on the end of GoG/Origin not Obsidian. They need to make a patcher over at GoG for you to download separately and Origin also preinspects any patch sent by the developer of their products. With Valve they receive the patch and release what is sent to them as soon as they can.
You chose the platform that uses the longest process so unfortuately you will have to wait for GoG to inspect and create their own patcher for you.
