It really depends on how far into the game I am. I played DMC, first room, I have to collect all the red orbs to get through the door. Find all of them except one. Turn it off, give my brain a chance to relax, try again a week later. Same deal. I give up forever and have never given a DMC game a second look - that's plain bad game design - finding the last red orb isn't a fun type of challenge, having a puzzle challenge in a game (and this wasn't even a puzzle) about slashing and shooting enemies in gratuitous fashion isn't fun either - the only acceptable fun is the insanely hard boss battles - I had to try the first boss in Ninja Gaiden Sigma at least 50 times - it was hard but at least it's something that's satisfying to finally beat, finding the last red orb I just quit. When playing Klingon Honor Guard I was about half way through and couldn't find a secret door because there wasn't a visual clue and I was expected to miss an enemy and open it but didn't actually miss them, so the door never opened. I used a passwall cheat to move on.
