We’re kind of cheating here, because Sonic 3’s opening zone is memorable for all sorts of reasons and not just because you meet Knuckles for the first time. As you dash through the verdant zone with Tails in tow, you’re blown away by how lush and gorgeous Angel Island looks. Before long you encounter a mid-level boss which bombards you with rockets, leading to a wall of fire that completely obliterates the once-leafy island. Things then take a more sinister turn as the tranquil scenery is replaced with a scorched wasteland.
