I wanted one so bad, I once borrowed one and played Mario 6 Golden Coins and loved it so much, but at the same time wished a certain hedgehog was on it.
I was told it needed to stay plugged in to play, which a gameboy did not so was angry my friends wouldn't be able to see me being cool at school, and the size of it was huge. But soon as I plugged it in and inserted Sonic the Hedgehog 1 into it...I was blown away.
He had same things as me, so we would head to head alot, Micro Machines on the GameGear being the favourite with laptimes. One day I came to visit him...he had it up on his television. I was in awe. He handed me a black controller with three buttons on it and told me to carry on while he went to the toilet. Three buttons? I instantly knew which button made me go, and I was soon playing the game, not thinking anything of it except that maybe he had bought a cable of some sort that allowed him to play the game on the television.
When he returned he asked me 'So? What dya think?' I said love it man, he nodded and pointed to the black box under the television. 'My Megadrive...So....when you gettin' one?' I gasped. He explained it was a GameGear that was better...but could be played on the tv and with better and longer games. I didn't believe him until he slotted Sonic 2 into the console and switched it on. I was pretty much close to killing him and stealing the machine he had. The graphics so clear, so colourful, so....AMAZING! I wanted it so bad!
