Sonic Adventure 3 does not exist.

In terms of gameplay, this game is your best bet. However, plot-wise, it is not SA3, as it is a (now uncanon) soft reboot for the Sonic franchise.

In terms of plot, these two games are Sonic Adventure 3, as they close up Shadow's plot. Even then, they do not give insight about other Sonic characters.

Sonic World Adventure is the closest thing to Sonic Adventure 3. The name fits, but the gameplay and plot do not. They are boost-style games, not adventure-style.

If you want Sonic Adventure 3, look at how the first two were made. We would need a perfect blend of those two games. We'd need a way to appeal to all fans. Knowing how AWFUL Sega is right now, they would NEVER make a true Sonic Adventure 3.
