My failures consist mainly of first person shooters. The fact that under heavy fire, I will pull out the machine gun of all things, swing across the screen with my finger hard down on the firing button out of pure reaction and kill most, if not all of my allies, the survivors being heavily wounded. I'm largely hated and excluded from online team matches because of this.
It gets better:
You know those big guns that shoot explosives? It's typically my bright idea that when out of sensible ammo, such as, say a shotgun, I'll come around a corner and fire a bazooka, however, these have a half second delay time far too often and by then, I've strifed back behind the wall only to fire that missile dead center two inches from my face.
There's also the capture the flag scenarios in which I somehow often manage to get the enemy flag (probably because the one thing I am good at in FPS is that I'm able to not get hit), run back to base only to somehow circle while running to evade enemy fire and end up back in enemy base to be gunned down.
Other notable things I've done:
-Forgotten to throw a grenade. While standing by my team.
-Set land mines and later walk on them.
-Completely miss some guy who's out of ammo and running at me with a knife from far away despite the fact that I have a fully automated machine gun.
Yeah... meantime in roguelikes, there's been only one death I can think that was really, really stupid. Heading into lair of the boss of the fire branch of hell in Crawl, I was looking away talking to a family member while I put in the commands for my character to eat a peach since he was hungry. To eat, hit "e" to wield a weapon, hit "w". I wielded a banana and died horribly not realizing why I wasn't doing jack damage.
