I think for me it’s Harvest Moon Friends of Mineral Town. Even though the triggers can be a bit bugged at times the achievements act as a great way to track progress like character events and your relationship level with people of the town. It’s not super hard to check when dealing with the bachelorettes because their heart level is shown but seeing exact percentages is nice.
They have also incentivised me to play a lot NES games I may not have normally played like Abadox.
Only recently got into this amazing system! Going through a Dragon Warrior/Quest kick, so I’m currently 90% through the third game.
Loving the “out-thereness” of some of them. Like taking the princess to the final boss instead of home. It had some unique dialog that I would have never known about if not for the achievement.
