As far as single-player games are concerned, I realized I have a sweet-spot of ~100 hours when I get somewhat tired of it, and ~150 hours when I’m just done. I don’t know anything about the story of Xenoblade 3 after the snow area because I crossed that threshold and just stopped paying attention. I just wanted it to be over. I had just played the Live A Live remake before that and I realized how much I miss the pacing of classic RPGs.
On the other hand, I’m closing in on 500 hours in Monster Hunter Rise. I have no problem casually grinding out games that aren’t a long-term story-commitment.
I’ll take you back there, but I’ve only ever travelled through time once, so safety is not guaranteed.
