You’re not offending anyone. But this idea that a game “dies” if not constantly updated is just weird to me. D2 hasn’t been updated in decades yet plenty of people still enjoy playing it. Titan Quest hadn’t been updated in years yet people still enjoyed playing it.
Personally I’m with Medierra on this. The team need/want a break from ARPG’s. Would you rather they keep plugging away and either the quality of the game goes down because they’re burnt out or many of the team leave because they just can’t face working on GD any longer?
Medierra also said many years ago that their main aim is to keep the company going and to him the best way to do this is not to rely on one franchise all the time. Hence Crate working on other projects in other genres giving the company a broad base to earn money with.
I’m not saying your idea isn’t interesting, but Crate have said they’re happy with where the game is now. I personally am not sure how much it would add to the game’s “life” either since very few players actually play in the Shattered Realm.
