I never had the opportunity to play the first Sonic games in my childhood, that is, I can't really give an opinion on that.
I went to play my first Sonic game on my PS2 (that I received in 2011) I played games like Sonic Riders and Sonic Unleashed. Comparing these games to those of the past, the producer doesn't really know what to do with the game anymore, they are totally different styles, of course PS2 was already an advanced console at the time (but there was a Sonic game that was a board race lol)
And it's true, one of my favorite characters is Shadow, just like you said, these characters should be used more in the series. I really wanted a game where Shadow was playable and well played, I love this character
Look, I don't know if you've seen this, but this is just terrible, what do people have in mind to do such a thing?
I didn't play it, but I saw several videos about this modified version.
Haha I'm glad you saw it Prison Break, even if it was just the first episode, keep going, you'll be impressed
