I could literally write a novel based on my problems with my OCD while I am playing videos games. For example: In Blockland, if I am building a wall and I misplace a brick, I have to restart the whole wall, and I can't get it perfect on an odd number because then it will bother me. I also don't luck things that are uneven or don't match. And my ammo has to always be even. Like I said, that is just some basics.
