Yeah. It plays well with Sonic Rumble.
I also notice it plays with Sonic Adventure 2 Battle, but not Sonic Adventure DX. I wonder what SA2B has that SADX does not?
Their port quality is indeed different.
SADX was often criticized by fans for being a lazy port of the older 2003 Director's Cut release.
It also lacks the original Dreamcast lighting and visual charm, that's why many fans were using mod like BetterSADX to restore Dreamcast graphics.
