There are several options in order to purchase Sonic Adventure Battle 2 for PlayStation 3. Some examples would be "Amazon", "eBay", "Rebuy", "SteamPowered" and "Yopi".
yes you can its in the ps3 shop
Depends on which game you're talking about, but yes. Sonic 2, 3, Sonic & Knuckles, Sonic 3 & Knuckles, Sonic Adventure, Sonic Adventure 2, Sonic Adventure 2 Battle, Sonic Heroes, Sonic The Hedgehog (For Wii, XBox 360 and PS3), and most Sonic Games you can be. Usually, doing it requires the 7 Chaos Emeralds. However, in Sonic Adventure and Sonic Adventure 2, its' done as a special extra quest.
no
No at least not under that title
It is possible that Sonic Adventure 2 will be downloadable off of PSN as Sonic Adventure was released earlier this year. But no information has been released.
No it is for game boy
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.
Sonic Rivals is a 2.5D platformer for PSP, and Sonic Adventure is a 3D platformer for Dreamcast, Gamecube, Xbox 360, PS3 and PC.
Sadly, like every game since Sonic Adventure, you can play as Super Sonic ONLY in the Last Story.
