The first time was about half a year after the release of Mega Man 4. The SNES was the next big thing.
One day, I went to a local trade shop and trade the following six games:
Mega Man. I traded Exodus Ultima two weeks after getting it for Xmas. I felt like a basterd because my mom spend money she didnt have.
Mega Man 4 that i played like crazy the last 6 months.
Renegade don't remember where got it but was my 2nd best right after:
Double Dragons 2:The Revenge. I got it after  my mom took me to a game store and said: Pick any one you want.
Spy Vs. Spy Went half the city on bus to get it at 20$ new and waited an hour because they couldnt find another
than the one on display. Became one of my favorite.
Phantasy Star. A b-day gift from my dad so I could stop renting it.
All of them for Super Ghouls N' Ghosts at 79.99 new but opened with 5$ discount.  
All excited, I went home, threw Super Double Dragons over my shoulder and put the game and at the same time,
Turn on the T.V. Pump up the volume, sat down and saw RPM Racing at the screen. I looked at the cart. and it was RPM.
I started to cry like a baby and showed the cart. and the box to my mom and she agreed, not the same.
We went the next day to the store, only to be called a thieft for trying to swap games.
I've thrown the cart. at her face. went behind the counter and tried to take both my Mega Man thatt were marked at 54.99 each.
On an orage sticker but my mom stopped me. I cried for days and end up in a mental hospital for a month.

Second cry and more about me coming up!
