This game is by far my favorite game of all time. There's just so much that I love about it - the fantastic level design, the tight controls, the incredibly vibrant visuals, the amazing music, etc. Modern and Classic Sonic are so much fun to play, the levels are so much fun to go through, the bosses are all incredibly fun (with a lone exception), the entire game oozes charm and is a great love letter to the entire history of the series, genuinely this game is something I can go back to over and over again and never get tired of it. I hope one day Sonic Team puts together an original game that has as much thought and love put into it as this game did.
