There weren't many things that I liked more than Sonic in my early childhood days, and this game was definitely the best of the bunch. I never managed to beat it as a kid, but it was always the one I came back to most often - there was just something special about it. The sceneries, the music, everything about this game felt magic and still does. After growing up, it's the only Sonic game I got back into for longer than a short while, having finished it multiple times.
