Another amazing Sega game, and arguably their final good one of the Sonic franchise. It is just as memorable and fun as the original Sonic Adventure game, but lacks the 'small' amount of free roam it used to have. You select from two teams: Hero and Dark, from which you play as 3 characters in a sequence of missions until the end-game and final boss, which I won't talk about as I wouldn't want to spoil it for anyone.
I played this game when it came out on the Dreamcast, just like Sonic Adventure, and was never disappointed. It as another one of those games I could play day in and day out and holds many memories for me. You are assigned a grade for each level, E, D, C, B and A - A being the best. There are 5 stages to each level with a different objective so that you won't be left with nothing to do. Unless your a pro like me of course;) Ahem, anyways...
Once all stages are complete with Hero and Dark stories, you unlock a final story.
Now let's not forget why we all really play any of the Sonic Adventure games...CHAO!
This game features 3 Chao gardens. A Neutral, Hero and Dark. Hero and Dark gardens can only be unlocked when you have raised a Chao with the respective sided characters. The Chao land features a school, where you can buy items at the Black Market, put your Chao into classes to be taught dances, drawing, instruments and other nice abilities or go to the Fortune Teller to get a badass name. Many hours will be spent here, just like in the previous game. You can send your Chao into races as always to win medals and items for your Chao and also put them into karate matches if you have the DLC.
All in all, it's an amazing game and plays smoother than Sonic Adventure did originally, however both amazing games!
