I love sa1!!!, While playing as Tails, Knuckles, and Amy kinda feels boring to me they're okay. I do actually like Big's gameplay I think it's a nice change of pace and a nice little break between replaying the same story beats over and over like you get from playing as Tails or Knuckles (cough cough Chaos 4). Big is just a nice relaxing time where you find fishie :). Gamma is also really fun and his story is pretty great. Gamma's time actually counts down and you need to combo together multiple enemies/objects in order to increase the time. Running out of time is almost never an issue though but getting a really big enemy chain is satisfying and he controls nicely. Lastly we have Sonic's story. This is a magnificant transition of the 2d formula to 3d believe it or not. There's shortcuts and secrets. Using sonic's spindash to find skips and go fast is really fun I like him. Also obviously the soundtrack is awesome and one of the best Sonic osts
