Diablo 3 was fun while it still felt new, which was back in the initial months of its release. I lost interest after that and I regret buying RoS, as the kind of game Diablo is does not appeal to me in the long run. Grinding upon grinding upon grind, is unbelievably boring, no matter how fun the combat is, you are still running endlessly through the same environments with an infinitely scaling difficulty slider. Games like that bore me, fast, and I doubt I will buy into Diablo 4 for the same reasons.
