The devs behind this game: "Hey! Let's advertise the fact that you can play as the T-Rex only to have players play as three other characters. Then! To add insult to injury, make the T-Rex the worst character in the game!"
You know what? It's not worth writing a long paragraph for this again like last time. This is the worst Sonic game I've ever played and it made me wanna quit the franchise for a while. Thank God the movies re-kindled my love for the blue dude.
