The original teaser trailer for 'Sonic Generations'.

I remember the first thing I did 2 months after that around 2011 was getting into Sonic News Network and looking if Espio was in the game. I literally scream like crazy lol, Sonic News Network was really fast at that time, but Sonic Retro was more accurate for deep things lol

Funny how this teaser appeared in the final game as the opening cinematic. 😭
