They haven't abandoned us, they're just being more selective. There's talk of bringing their Clock Tower remaster over.

Here I'm almost certain that's not down to Wayforward but Konami not having given the green light for a DRM-free version yet.

Could be the same for River City Girls 2 and, in that case, Arc System Works.

In general, it's often the owner of the IP that has the last word on what platforms the title using the respective IP or license is sold on.

The first River City Girls is on here though. And it doesn't explain why Dawn of the Monsters' DLC never appeared.

The IP holder may not have been staisfied with sales of River City Girls here on GOG. You would need to contact the publisher and/or get more people to buy the game here. Money is what publishers listen to the most.

Not enough money being made here for them to care? RIP us :)

"What happened?" --- They consistently treated GOG customers like second-class citizens by removing features for the gimped, second-class citizen GOG versions of their games, and then after doing that, they had the outrageous gall & audacity to whine & cry about the low sales of the inferior versions of their games that they put on GOG --- which of course, is entirely their own fault for gimping their GOG games, which happened due to sheer laziness and not caring on their parts, and for no other reason.

Hopefully they will never release any more of their gimped games on GOG ever again. If they don't, then that will be a great thing. :)

I imagine that GOG's headless chicken style of management didn't jive with them.

Seems the Dawn of the Monsters DLC finally got released on GOG:

Fingers crossed we'll see more Wayfoward game like River City Girls 2.

i hope you are not talking about the shitty achievements again

It is almost always about money.
