Bigby Wolf (f.k.a. the Big Bad Wolf), Unreal Engine 4, the predecessor
being available on GoG... would be quite an early commitment to releasing on GoG, since it's scheduled for 2023, though.
The amount of activity I'm seeing on it makes me think it's under intense development and probably a soon-ish release, but time will tell.
Actually, now that I think about it --- there is a game called: CLANNAD
Well, Clannad was a rather known drama anime series, oh, about two decades ago. Sort of a purposeful tearjerker, but still nice. The game appears to be a visual novel adaptation of the series. Perhaps the creators of the anime were also fans of the band? :P
