I asked about the games coming to GoG and they responded this morning with the following
We do want to, but depends on GOG.
So you want to see the games on GOG, add them to your wishlists, and ask your friends too to add them.
The more wishlists the higher the chances they will be published on their store =D "
So i suppose up to us if we want these games here. Would love to see some of these old classic games here
I got this same exact email recently as well. I also got a followup email from the main Piko one.
