I don't know how I went 30 years without playing the Sega Master System until this week, but it was worth the wait! It's like everything I wished the NES was when I was a kid, complete with Sonic the Hedgehog and Mortal Kombat! =O
It is an AWESOME system. I need to bring mine out again. I managed to buy one that had never been opened about 10 years ago at a local thrift store. I always liked the design of everything too.
