I have an embarassing one
I was 11 when I got my first console, a Sega master System, I got it for christmas, It was the original one with duck hunt & hang on built in.
I didnt get any carts for christmas & I was happy playing the built in games, around February time, I had saved up enough money to buy my first cartridge, (Rampage).
I couldnt wait to get home to play it, bearing in mind I had come from the C16/C64/Spectrum generation & was used to cassettes.
When I got home with 2 of my friends, I plugged the game in, but not knowing how these things worked!!!
I didnt push the cart down all the way in fear of breaking it, I switched the SMS on & I was greeted with the hang on/duck hunt select screen!
Rarther than being rational about it (& being 11) I kept turning it on & off, & then I had a massive paddy!
VERY EMBARASSING, as my mates were watching!
I remember getting so worked up, I was actually crying & shouting things like "nothing ever works for me" & I remember throwing the box across the room!
then my mum came in & pushed the cart down & switched the game on!
& another one,
When I was about 15/16 Street Fighter 2 was all the rage & a friend from school was very good at it (Arcade Version)
There was a SF2 cabinet in our local arcade & one Saturday I had wandered in, my friend from school was there playing against some random bloke who thought he was awesome at it, my friend was getting hammered & was hardly doing anything.
This bloke was loving it & was laughing & gloating about it, when they finished my friend handed over some money, (they had been betting on it) then he asked the bloke for one more try! double or quits! they put all their money in, more than £40 if I remember right,
They started off again, first round went to this bloke, then my friend looked at me & winked.
then all hell broke loose, my friend had been hustling this guy all along & then just ripped him to shreds he was smashing his character into the ground & pulling off move after move, this guy was panicking & mashing the buttons, my friend pulled off 2 Perfect rounds.
The bloke was literally crying!
