Are they ever going to update the game reclaim thing on their website?? I've invested TOO much on steam, but i'd really love to jump over to GOG if i could. But i'd be leaving behind just too dang much. If i was able to reclaim even just half of my library, i'd be willing to jump ship 100%. Looking at the page, it hasn't been updated since september 2017... is it dead?? should i just forget it?? Will they ever bring it back and add more games??

The Reclaim system has nothing to do with Steam, it is for game CD keys. While some of the Steam games listed DO provide CD keys, that's not the purpose of this feature.

I think you're looking for the GOG Connect feature.

And well regarding GOG Connect it's a feature which ocurrs(ed) every few months.
With a big library and being there from the start one would have gotten quite a lot of games on GOG.
Not sure if the linked list is "totally complete" and shows every single game ever being on GOG Connect but it is pretty extensive and offers a good grasp.

The bad news is GOG Connect is time limited and you only receive the games if you would have claimed them during the given periods you so if you missed it in the past you missed it for good (it's not like you get all the games they given away in the past).

With Galaxy 2.0 it's still possible to see your steam and gog games at the same place though.

Why do you need to jump ship?
