I have not seen this question when searching, although someone here might be able to point me to it. I found a related one here
Situation: PC walks into a room and wants to investigate to find any clues or whatever. They roll a 5 and lets say +3, which results in nothing. However, as a real person would, wouldn't the PC want to look again? In real life, if I'm in a room and I'm wanting to find something (imagine an escape room), I am going to continue looking around the same room. IE investigating it multiple times.
However, that seems broken, or at least too gamey. But I can't effectively call if gamey if it's a practice people do in real life.
So: Can you investigate the same room twice per RAW?
