I have read numerous topics including abandonment, slow update rate, radio silence and different more kinds of discussions about this. Mostly the reason behind this was because of copyright/fear of community using that for the opposite reasons.
As I would gladly contribute in all kinds of projects GH is up to, I am still pretty concerned that there isnt any other way of helping the game to cherish except of payments like energy and deluxe packs.
Community would be always ready to help whatever there is to help with. I just hope they wont hesitate to ask for help, because if they did that long time ago, we wouldnt sit on below thousand players and we would mostly have released more content than it ever was released in all those 8 years.
Not to mention that some updates took years to come out, so that would be enormous deal both for community and GH.
.............and now you get to experience "abandonment" and "radio silence". What an exciting time to be alive!
