As classic as the first.
Cons: BUT HARD! The game can hard as well, but it's still SPocioUS
Storyline: After defeating Robotnik in the first game, Robotnik returns and he has a deadly weapon: The Death Egg (it's like the Death Star from Star Wars) and he's arrived at the West Island (think that's what it's called). When Sonic learns of this he sets off to stop Robotnik. But he ain't alone... he's got Tails, a 8 year old fox on his side! Sonic and Tails must stop him before the Death Egg fires!
Classic.
Graphics: The graphics are just as good as the first. The game is more colorful and brighter than the first game. The addition of Tails makes the game have a upstart in the graphics . Long designs make longer levels Long level desings... Now this game is detailed. HIGHLY DETAILED. It's more detailed than the first game of course. Graphics are, overally, beautiful for the Genesis. Great graphics. And we can also see.... Super Sayians! Boom! Kamehameha!... Well you don't see them actually but Super Sonic resembles a super sayians a lot! Anyway, this is also one of the great looking Genesis games.
Gameplay- 1 word: Wow. It plays a lot like the first one but with a few improvements. The co-op play is fun to play with family and friends. It is Sonic and Tails. You can be Sonic alone or Tails alone. The spin attack is here and a new attack came: The spin dash. Now you can witness Sonic's ultra super hyper fast speed quicker than the first game. Sonic becomes a ball and dashes, making a burst of speed. It can kill on ground enemies. Another way to see great speed is with Super Sonic. He is so fast that it's hard to control him. He can't brake that easily but a least you get to see true speed! Tails is also quite fast but can't keep up with Sonic, the fastest thing alive! Sorry. Ehem. The boss fights are... really fun. But this game is kinda easy. I mean: the game is easier than the first! Most of the boss fights are easy. I'm on the Metropolis level (forgot which act but it's NOT act 1!). Multiplayer is fun. The special stages are good but hard. Those tunnel levels... they're impossible (well they're not impossible. Just sayin' dat they're hard). But I can complete the game without the Chaos Emeralds. Does that mean no Super Sonic? No. I can use cheat codes.
Sound: Great music but the sound is not as good as the first one. That's all I can say about the sound. Great Sound effects though.
Overall: It's better than the first... This and Sonic & Knuckles... are my fav 2D Sonic games (Sonic CD will, hopefully, be added to the list). It faster than the first. If you think you're a true Sonic fan... play all of the good Genesis games!
