I did and still do...I think it was 1986, and saw the SMS after I got into the NES. Once I played it, I did not want to go back to the NES, so I sold everything I had for the NES, and used the money to buy lots of SMS games. Did not care for the Light Phaser games back then, since I bought the Base System package. But I did get the 3D Glasses and its games. Even though the games were more expensive in general, I really enjoyed playing the SMS. Once the Power Base Converter came out for the Genesis, I sold my SMS system but kept all the games. On eBay, I was able to purchase the Light Phaser and all its games. Plus, I purchased most of the EU games that are compatible with the US SMS, and I repurchased the Sports Pad to complete my SMS collection. I have most of the SMS games released in the US along with most of the EU-only games released before the Mega Drive was released in the EU.
