I asked the dev of Blackbay Asylum (steam game) if it would ever come to GOG, he said that it was up to the publishers not him to make that decision and didn't elaborate, so I made a wishlist for it here anyway, but it didn't garner much interest.

It could be that new devs consider that due to the name, maybe GOG just concentrate on "old" games.

Everytime Blackguards goes on sale, I don't have money :(
Blackguards has been on sale many times in the recent months though. Probably it's not being sold that much? Its normal price is a little too expensive imho...
