God damn how is it that Sega has never released a Sonic Adventure-style game with that kind of online multiplayer? It's so freaking obvious and yet we've never seen it.
Some of the gameplay mechanics look a bit... unnecessary? Like riding on vehicles, at least at speed. And I've always thought the Sonic Adventure rail grinding was tedious. But still overall it looks like a fun adaptation of the 3D sonic gameplay albeit with a slightly dated-looking art style.
