What do you do after you realize you screwed up in a game?

• You missed the one and only opportunity to have a very useful item/powerful weapon
• You wasted a ton of time doing something you thought would pay-off, but end up being a big waste of time
• You wasted all your cash on an item/weapon that you later get for free or get something even better
• Your only save is when you have 1/100 health and enemies are surrounding you

Restart at the last checkpoint and do it again.

I don't do anything, because those things never happen to me, FOR I AM KING!!!

I cry myself to sleep 

Cheat.

the first one: reload my last save and get it
2: that sucks for me, i would probably take a break
3: go and earn some more money so i can spend it all on nothing again
4: keep reloading til i can get out of there

I simply just curse.

" Beat my wife naturally. "

Walk over to the corner of the room and adopt the fetal position.

Replay the whole game from the beginning, depending on the game and how much time I've spent on it though.

The first three don't really bother me that much.   They bug me a little, of course, but I don't let them get under my skin enough to make me reload at the last save point or whatever.
 
If I get stuck with very low health, I'll usually just keep reloading that save and play better until I get through it.  Of course, I rarely ever let things get that bad in the first place.

I keep a subconscious difficulty scale in my head while playing. When I F up big time and I'm limping through a firefight I just convince myself that I have to focus as if I was playing on hard, and I usually make it out OK.

I KILL

Turn it off and run away crying, and never pick up the game until at least 3 months later.

I press on no matter how horribly I screwed up.

I mutter to myself in a low, menacing growl, "I don't need this fucking bullshit."
 
I then go to sleep.

Go into denial.

I expand and get siege tanks.

If I miss something I'll make sure I dont on the next playthrough.

Open up developers console and alt tab to open up Firefox.

This usually happens when I play Metroid. 
 
What I do is:
 
1) Realize that I fucked up
2) Throw my controller 
3) Shut off the game
4) Rage for the rest of the day

I accept it and cry. I have screwed up my Oblivion game multiple times. Low level and any time I slept I got killed by the dark brotherhood ghost. Another time I became a vampire as well as having a curse that drained all my energy so I couldn't fight my way into the Mages Guild to cure my vampire curse. Hated it!

Continue slogging through the game, living with my mistake and hating myself throughout.

I've always thought that's a severe flaw with the game itself, if it doesn't let you know that you're missing something you can't go back to. Final Fantasy was the biggest culprit of that for the longest time (and may be still...) where you'd miss the ULTIMATE SUMMON if you didn't bother drawing or whatever from a certain creature.
 
It's a design flaw. It makes me mad.

I find the nearest wall/person and beat my head against it repeatedly.

I've restarted Dragon Age twice because I was unhappy with my characters facial hair.

I get pissed off at everyone and everything for hours... then i go back to the game and finish it in one sitting :)

usually restart from my last save file from the game.

I break something and cry. Usually because the thing I broke was expensive, and because it was hard and hurt me when I broke it.
