The many releases of Sonic Adventure 2 each have differences which make them visibly dissimilar, even though they all control almost the same. This page will broadly cover the differences in versions. Since most popular categories are timed by IGT, any platform is viable for WR runs. If there are specific differences which are useful in the run, they will be covered in the respective stage page.
