I have to admit, I love the modern Sonic games, but I also have a fondness for some classic Sonic games dating back to when I was about 5 or 6. This of course was the very first Sonic game to be made for the Master System, and some noticeable graphics will tell you why. All Chaos emeralds are within act levels, instead of bonus levels like in the Genesis Version, and they all appear to be exactly the same, in colour and appearance. Also, all checkpoints in the game are not as star posts, but as boxes displaying a downwards arrow. There are also very few invincibility or power sneakers boxes, so Sonic will have to take extra care when navigating through the levels. As for the overall difficulty of the game, its actually quite easy, and I'm not saying that because when I was younger I consistently went through an entire game without losing a life. The enemies are not too hard, there's not too many dangerous obstacles, and there are opportunities to get lives and continues when in bonus levels. What you will have to be wary of, however, is if Sonic takes damage with rings, ALL are lost. A familiar story of course. Robotnik kidnapping animals, turning some into robots, you guessed it, he wants to rule the world, possibly one of the first ever times he tried when you think about when this game was created. This is a classic game I keep coming back to play constantly, I think its awesome. In terms of overall addictiveness, its my game, and I like to hear the game music being played during a level. Overall, this game is well worth a try.
