I always move and shake the controller too much, like if I was playing with some virtual reality machine... I don't know if you get what I mean.
I intentionally avoid reading manuals and instructions, and find myself in trouble later.
It happened more than once that I invited someone to play and then I left them in front of the console all alone while I started other activities, like reading a book, surfing the net, chasing furry mammals living in my house (felines, I mean felines...) etc.
I don't accept suggestions and get pissed if somebody tells me what to do in a game.
I can instantly start hating a videogaming character and enjoy when it gets killed. I can even plan to have it killed on purpose just for sadistic pleasure.
I could think of others, with a little effort, but I don't think this would help my self-esteem
