Just curious if there are any gog bundles ,like, Humble Fanatical Indiegala etc ?

Funny, I was thinking about the same thing earlier today!
GOG bundles would be awesome.

Never seen any. Only games I know that are redeemable on GOG from Humble are the Witcher games. I imagine they'd just host the DRM-free versions themselves if they were going to sell any such content otherwise.

I've had GOG keys in bundles before, I think on groupees or somewhere else. Very rare though. Not entirely gog bundles though, just a couple of gog keys mixed in.

Humble seems to also have GOG keys for War for the Overworld and Everspace.

There are bundle sales on GOG but it's slim pickings when you try to find GOG keys on other websites. Last big one was when Mafia 2 and 3 came out.

not likely, there has been a couple only. gOg's system for key generation and willingness to participate does not suite the market

I wonder if gog would do their own version of say the Humble Monthly, I would happily pay a subscription to gog each month to build my library, the Humle Monthly is incredible value for 12 dollars, and you can cancel anyime you want.

Closest thing I've seen is that if you buy a series of games, the site will kick in a discount. Such an offer is usually listed along the right hand side of a gamecard page.

But, no, they don;t call it bundles.

Gog doesn't like bundles. At one point GOG keys showed up in some bundles (in a few Groupees for example), but I haven't seen it happen since. The closest you can get now is GOG Connecting a Steam game you got in a bundle, but, well, obvious problem of not knowing if any game you get in a bundle will ever show up on GOG Connect.
