1. Sonic 3 & Knuckles I don't think I've played all the way through any other game as many times as I have this one. Number one my list for good reason. I'll still play through Sonic 3 or Sonic & Knuckles while sitting in class. In the past month I've played through Sonic 3 alone with all the Chaos Emeralds at least four times. 2. Sonic Advance The last Sonic game of its kind. The level design was great, and each one was compatible with any of the characters' special abilities. Once Sonic Advance 2 hit, the characters' abilities were more or less "optional", and due to the fast nature of the game, nobody wants to fly or glide because that will slow them down. Sonic Advance was the closest we'd got to classic Sonic in roughly 7 or 8 years. I can't not mention it. I also just loved the Time Attacking. Me and my best friend used to go back and forth trying to get the fastest time on Neo Green Hill 1. Good fun. 3. Sonic Adventure The game has aged horribly, but I'll still pick it up and play it every now and then. Years ago though, I loved the shit out of it, and enjoyed all the different types of gameplay. Yes, even the fishing was kind of fun. 4. Sonic The Hedgehog 2 A little lower on my list than some of you would approve, but I'm going to stand by it. It took everything the original had, and improved upon it. The Special Stages are fun (if you're playing as Sonic alone), and I love either zooming through or exploring each Zone (though if I had to pick a Zone to take out of the game, it'd be Oil Ocean. The music is annoying, and it's just too slow). Super Sonic was a sight to behold, and makes the game just...more fun. I'd say the only reason it's not 3 on my list, is because Sonic and Tails play exactly the same, but then again, if that bothered me too much, it'd be 5 or lower. 5. Sonic Unleashed (360) I hesitate to put it before any of the first four, but I'm not afraid to put it in front of some of the others. It's just...fun. And challenging. It requires actual skill and decent reflexes. The night stages have a wonderful combat system, that's a lot more in depth than it lets on. The platforming in both times of day is excellent. To be quite honest, it's the most fun I've had with a video game in about a year now (probably since Super Mario Galaxy). This is an educated choice, I've spent so much time with the game since last week. I've played all the way through it, and compared to a bunch of other Sonic games. I'd put it before Sonic Adventure, if not just because of how great the hub worlds are, but I'm already risking enough by putting it ahead of the original. Five worst? 1. Sonic Labyrinth Started it up, stopped it in about thirty seconds. Sonic was no faster than a sloth, and using the Spin-Dash didn't help too much. Fucking terrible. 2. Sonic Blast (GG) Someone tried to do prerendered sprites on the game gear, but didn't put any effort into the gameplay. Also fucking terrible. The Special Stage makes me want to vomit. 3. Sonic Drift It was both a terrible Sonic game, and a terrible racing game. It was just...boring. 4. Shadow The Hedgehog I tried to like it. Just could've been a LOT better. 5. Sonic The Hedgehog (360/PS3) Yep. And everything else is just crammed in between. I'd have the say the original game is 6th best, but you know.
