this game is a side scrolling game just like th original sonic games, but adds a new 3-D twist to the series.
The Bad: Way too easy> The minigame to get the chaos emeralds are sometimes so hard, u want too throw your ds on the ground and cry> u can only play as 2 characters, i was so looking forward to knuckles> a new villain Eggman Nega (Sega is so desperate now a days)
Final Comments: The game is fun with good music, but should have had more playable characters>
