This game is such an accomplishment, such an amazing pinnacle of achievement, and such a beautiful mesh of gaming new and old-fused together underneath the bright red shoes and fleet feet of the world's most famous hedgehog. This game has finally done sonic justice, and has all the intense action and fun of sonic adventure 1 and 2, with the addition of that classic platforming brilliance of the sonic 1,2,3, and knuckles era. The level design and adaptation are incredible, bosses are true to form, as well as the feel and overall atmosphere of the game. The levels are INSANELY fast paced...and feel actually well, FUN! I have been a diehard sonic fan for years, and have become discouraged with alot of Sega's decisions...however this game takes the cake; and rights all previous wrongs. All the glitches have been fixed, and the game flows so continually and fluidly-(without the stupid side characters or annoying mini missions). There are other challenges which allow you to purchase upgrades from the shop-including the complete original sonic 1 game from the Sega Genesis console.
On top of this..there is so SO much more...the bosses, the music, OOOH GOD THE MUSIC
I have never felt this much nostalgia from just one game...and if you are either a sonic fan or ever enjoyed a sonic game...then you HAVE to pick up generations today.
Sonic is back and, although he may have skidded, slipped, or slid a bit here and there, he is running harder and faster than ever before...20 years later and never better.
