This is the same reason why people hate the Werehog gameplay even though the Werehog is Sonic, the gameplay is a plodding beat-em-up where Sonic walks around the levels climbing and beating up enemies.
Likewise with SA2 Tails, instead of speeding and flying around the level, you were in a slow, plodding mech shooting down enemies. You weren't really speeding through levels and using your momentum to platform, you were playing a game of find the needle in the haystack. Instead of speeding through levels like Sonic, you were aimlessly wandering around a large level looking for Emerald shards. In the Adventure games though? The other characters' gameplay were entirely different genres (aside from SA1 Tails, which is one of the few gameplay styles the Adventure games got right). Tails was like Sonic, but he could fly, and Knuckles was like Sonic, but he could climb and glide. Wed 23rd Jun The difference between Tails and Knuckles in 2D and Tails in Knuckles in Adventure was that Tails and Knuckles gameplay in 2D was similar to Sonic but with a unique twist.Please note: We're only featuring Sonic platformers that have appeared on Nintendo platforms - be it as part of a collection or as an individual release - so you won't find Knuckles Chaotix or Sonic the Hedgehog Pocket Adventure or anything that's not a platform game (no Mean Bean Machine or Tails' Skypatrol shmup action or Sonic Drift karting, then). So, grab a chili dog and a companion from your ever more ragtag bunch of sidekicks, and let's check out the best (and worst) Sonic games on Nintendo systems. If you haven't rated your favourites yet, simply click the 'star' of the game you wish to rate below and assign a score right now. Even as you read this, it's entirely possible to influence the ranking below. Remember: the order below is updated in real-time according to each game's corresponding User Rating in the Nintendo Life game database. To celebrate his 30th birthday we asked Nintendo Life readers to rank every 2D Sonic game, and by combining the results with an existing list of the 3D games, we can now present to you the definitive ranking of every Sonic game ever - the ones that appeared on a Nintendo platform, that is (sorry-not-sorry Sonic 2006). Regardless of his myriad hits and misses, Sonic has proven that he has something far more important than merely his speed and aforementioned 'tude: Sonic's got staying power.
