This is one of the greatest video games ever, and there are only a handful of those. It has to be the first video game I ever played, and also the video game I played for the longest time. It kept me entertained for years, no other video game I had lived up to my expectations as this game did (other than Road Rash 2, Super Mario Bros, and Sonic 3 and Knuckles). Like Sonic 2 isn't cool enough already, there's also 2-player. And 2-player mode isn't just a small addition, either-it's just as fun as single player. Sure, there are only four small stages for 2-player, but those four stages pack a real fun punch. The new special stages are also funner than the special stages in Sonic 2's prequel. Although Tails can't exactly use his ability of flight, it's still pretty fun if you play with a friend, because Tails can really help Sonic. He can make the boss fights easier, he can kill badniks before Sonic can devastatingly crash into them, and he can also collect those rings that Sonic doesn't want to get because he doesn't want to destroy his ring total. This game is purely amazing, and I think it's more of a classic than the first in the series, the one and only Sonic the Hedgehog. Out of all of the Sonic characters out there, Tails and Knuckles had to have the most awesome debuts. I actually still play this game from time to time-it just never gets old. Sometimes, I don't even have words to describe how fun it really is.
