YMMV / SegaSonic the Hedgehog

• Awesome Music: Trap Tower's theme, which was even brought back in Sonic Mania Plus as an incredibly jazzy tune for the Pinball Stages.
• Cult Classic: It has a small fanbase due to its gameplay along with its historical significance amongst the franchise.
• Disappointing Last Level: Eggman's Tower is a much less varied level than what preceded it and the traps there (which work just like the ones in Trap Tower) can hit you twice per mistake. And when you reach Dr. Eggman, there's no fight with him — he just sets the place to blow up and runs away. A time-limited run towards the exit in a simple, featureless path finishes the game.
• Magnificent Bastard: Eggman's objective in this game is to kill Sonic, Mighty and Ray. He starts out by successfully kidnapping them before imprisoning them in Eggman Island, an entire island designed to kill them. Then, he attempts to kill them in their prison with an advancing wall of spikes. When they escape, Eggman tries to kill them in the most over-the-top ways through the levels, with a giant ball of lava, falling giant stalactites, collapsing sand areas, giant rolling cylinders, boulders, trapped ladders, water and spike mines. He also traps the bridge leading towards his tower, expecting the heroes to cross it, and said trap ends up working. When the heroic trio confronts him, he successfully escapes and activate the tower's self-destruct sequence with only 20 seconds to spare. Leaving Sonic, Mighty and Ray screaming and panicking through the whole game, Eggman, despite being hammy and laughable, reminded them that his I.Q. of 300 wasn't for show.
• Older Than They Think:
  • Sonic Adventure was, for many gamers, the first Sonic game they played with voice acting. SegaSonic, however, preceeded Adventure in voice acting by at least five years, and even then, it still wasn't the first game to give Sonic a voice: that honor goes to WakuWaku Sonic Patrol Car, which came out in 1991.
  • Contrary to what some believe, Mighty's first appearance was this game, not Knuckles Chaotix. Even more extreme would be Ray, who would otherwise be absent sans one cameo in Sonic Generations until Sonic Mania, where he was added as a DLC character in 2018!
• Spiritual Successor: The game's design is based on Marble Madness, an isometric puzzle game that is similarly controlled with a trackball.
• Visual Effects of Awesome: The animations for the game are pretty good, especially for a game that came out in 1993 and are still fun to look at to this day.
