I didn't know until 2023 they made a 3ds portable system but the game is okay the rank of stage don't make sense like it not about died in a state you get a A rank nope on 3ds it about how fast u go you can't buy skill in the 3ds can't change music on any stage the final boss is better then the x360 and ps3 I don't mind having moder sonic in 2d but why the whole game stage every got to be on 2d only 3d is the final boss and special stage that it can't run around the hub space can talk to friends oh and the rivals battle suck why is it a race like silver can teleport but shadow cant he can free time silver can throw stuff at moder sonic shadow doesn't do that he just boost that it good thing in the next generation shadow is cooler overall this game is ok give it a 3.4 star because things they forgot on the x360 and ps3
