Because that game is so immensly strange that sega decided, screw it
There is no Sonic Adventure 4 Battle, there is Sonic Adventure 2 Battle but that was released 8 years ago.
No as Sonic Advance 2 came out after Sonic Adventure 2 Battle and Sonic Adventure 2 Battle was only made to be compatible with Sonic Advance.
There is no such thing as Sonic Adventure Battle 1, nonetheless no Sonic Adventure is playable on Sonic Mega Collection.
Sonic adventure battle 2
...Sonic Advance 2 Battle doesn't exist. But either of the following games it could be are not on XBox, anyway. -Sonic Advance 2 is a GBA exclusive. -Sonic Adventure 2: Battle is a Gamecube exclusive, although it was a port of the original Sonic Adventure 2 on the Dreamcast.
Sonic X's first season sports an original storyline, and the second is mostly based on the Sonic Adventure games and Sonic Battle. Sonic X doesn't follow the story of Sonic Advance games, though it does feature Cream and Cheese from the Sonic Advance series.
there is sonic adventure 3
Yes there is a sonic adventure 2 battle for the gamecube. I know because I have it~
Sonic Adventure Battle (DC/GC) and Sonic Adventure Battle 2 (DC/GC)
sonic unleashed has a couple things in common with sa1 but not really sa2 not much if you get it for the wii but a bit for 360/ps3 I suppose that Sonic Unleashed does have a sort of related storyline towards Sonic Adventure 1. Sonic Adventure 2 does have a way different storyline.
Rouge can be played as in... Sonic Adventure 2 Sonic Adventure 2 Battle Sonic Battle sonic riders That is all I can think of.
No, Sonic Adventure 2 is only on Dreamcast and Gamecube as Sonic Adventure 2 Battle.
