The "first hour feels like a job" problem is the real test for me too. If the basic actions are satisfying before any reward structure kicks in, I can tolerate some grind later; if not, no unlock schedule keeps me around. That's part of why Minecraft still works for my short sessions, as you said, it doesn't punish stopping mid-task. On Deron and Nin Online, I'd frame it less as patience and more as whether the routine itself is pleasant, since a routine you dread isn't a hobby.
