literally pointless. I remember growing up hyped for episode metal because metal sonic is one of my favorite sonic characters, but this was just 4 levels from Sonic 4 with metal sonic that plays the same as sonic, and means nothing. What a worthless game, at least it's free if you have episodes 1 and 2
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)
I'm a sucker for being able to play as the bad guy in video games, like Meta Knightmare and Dededetour in the Kirby series. The cool factor of being able to play as Metal Sonic wears off once you realize you're playing him in Sonic 4 Episode 1 levels, and he's functionally identical to Sonic. If you want to have fun playing as Metal Sonic, download a fan hack for a better game, or play SADX and SA2B.
