I’m aware of extrinsic motivation vs intrinsic motivation, about the potential upsides and downsides, the potentially positive or detrimental effects of achievements.

I often do chase or consider achievements, but also explore games and their limits or what they cover anyway. I do like completing, especially if 100% is feasible. Other times I ignore them and focus on the game. If the game is not very captivating or interesting, I often don’t care much about achievements.

I did find incremental progression games interesting in how they make the extrinsic motivation, the numbers-go-up system, the core game mechanic. It’s interesting to explore and be mindful of how that can be fun, but in a different way than creative, exploratory, or story games. Of course, some mix both systems.
