General Sonic is Terrible Thread

[NICKtendo DS]

There was a time where multiple characters were done right.
Play as Sonic for a fast-paced, more risky game where speed is the reward for skill. A speed-run character.
Play as Tails for easy exploration and easy gameplay overall, great for beginners.
Play as Knuckles to open alternate paths to new levels mixed with the old. Combined with harder bosses and different skills, he's a good choice for veterans.
Sonic 3 & Knuckles was fun for me to 100% with all 3 characters. It didn't feel repetitive. It felt fresh.
I don't get this thing where you can switch characters mid game. The characters become nothing more than tools, just like the fire & ice gimmick. See a fire icon? Use fire. See a hammer icon? Use Amy. There's hardly a difference. Switching is most likely mandatory anyway. The way I see it is that you play as 1 character dressed as 5.
