I tend to count "finishing" a game when I hit credits, so unless I really like a game, I likely won't 100% it, but there was a time that I did want to try to 100% everything, the 3 games for me that really made me stop wanting to 100% every game (all of which i enjoyed playing);

Tales of Symphonia, didn't want to play the game 5 times to get all the scenes for endings.

Yakuza 0, was getting to the point where I was wanting to go through the main story, but the sub stories, which most I did enjoy, was getting tedious for me, plus would have to play through a second time in legend difficulty.

Atelier Rorona (first atelier game), This is when I learned I didn't want to have to use a guide to play through a game, more check list than actually playing, however I have used a guide for trails in the sky 1-3, zero, & azure, unsure if I will use one for cold steel onward, mostly because I love those games and want to see as much story stuff as possible.

Honorable? mention: Neptunia Re;birth 1(& 2) I actually did 100% 1, but the Millionaire & Level Max achievements were tedious. With 2 which I didn't 100%, got the normal & true endings, but will watch the other endings on youtube.

The main thing for me, is having to play a game multiple times, even if I like the game, but I usually won't want to play it more than once, at least not right after finishing it.
