Regardless of what game I'm playing, I'll get frustrated if:
A) I know I can do better than I currently am.
I'm losing due to cheap tactics.
Let's take FIFA for example. If I'm simply being outplayed, that's fine. I can lose 3-0 and be fine with it. If I lose 1-0 to someone I've dominated against however, that's me done for the night. I'll get red cards all the time and try stupid shots. The same thing happens in FPS's.
