All the key Sonic titles are here, and in full form, making this a must have for anyone remotely old-school.
Gameplay: The game's controls glide smoothly as you guide your blue speed demon through some incredible locales and dangerous obstacles. The sense of speed is just plain incredible and some of the platforming action is some of the best ever. The games have been perfectly ported to the PS2 to make it the perfect Sonic experience. Not every title is good however, the original Sonic games (1, 2, 3, and knuckles) are great, while the other titles and the Game Gear games leave a bit to be desired. Dr. Robotnik's Mean Bean Machine was Sega's answer to Dr. Mario and doesn't really click.....Either way, the gameplay is great and the controls for each title are as good as they can be. 10/10.
Graphics: The graphics in this game are colorful, with beautiful designs and textures. They're by far some of the best of the 16-bit era. Every title has great visuals for it's time, like Neo*Geo quality. Younger people may not be able to appreciate the quality of the games, but if you can appreciate the technology of that day and age (which wasn't too old to begin with) you won't be dissapointed in the least bit. That's why I give the graphics a 10/10
Sound: The soundtrack in this game is up-beat, unique, catchy, and really good. It's got a techno beat but you'll be humming along to it in some instances. The game's sound effects are incredible here too, and thanks to the excellent porting to the PS2, the infamous: "SEGA!!!!" at the beggining of the game is in tact, and never sounds tinny or canned. What else can I say for sound? 10/10.
Value: This is the best aspect of the game. You're getting A TON of content here, seven Genesis titles, six Game Gear titles, plus a bunch of different unlockables. The unlockables are past Sega games that were cult favorites or just old favorites. All the content for $20!??! You really can't find a better retro collection. It's all good, even though there are a few lemons. 10/10.
Bottom Line: The game is for everyone. Amazing titles, with better gameplay and awesome graphics. Anyone looking for a great bargain would be stupid to not pick this one up. 10/10.
