In your opinion, what is the saddest and most memorable moment in the franchise?

Me: I confess that I don't have much experience with Sonic, after all, I discovered the franchise a short time ago, back in the first film, but I really developed my passion for the franchise with Sonic Frontiers. Well, my most memorable moment in the franchise was definitely the Sonic Frontiers Final Horizon DLC. I jumped for joy when I saw Super Sonic 2 and Cyber Sonic. I felt like a 5-year-old at that moment. I was very lucky to have been able to buy the game and to have followed the Frontiers updates closely. It was a video game journey that I will never forget.
