I'm not as hardcore of a Sonic fan as you are, but yes, I do remember the good old days. I used to love the old Sonic games, they were so much fun. I remember, back before my parents let us have video game consoles, we got one of those fake systems that had a few sample games on them. Sonic was on there, and I would sit there for hours trying to beat the game! Haha.
As for the newer games. They're...alright. Defenitally not as good as the older Sonic games, in my opinion. They just seem different, and not as classic to me. I have played some and enjoyed them, though. So not all bad! I just prefer the older games, is all. ;D
