When they titled this one in the same fashion as Ep. I & Ep. II, I assumed it would be similar length. I'm both happy and sad it wasn't. I love Metal Sonic, but when the entire Episode is just playing through the worlds of Ep. I, it grinds my gears a bit. Still, a fun little playthrough and a decent explanation for Metal's reemergence after his defeat in Sonic CD (though the continuity confuses me for the story of Chaotix's final boss, but questions for later)
