People who argue about that are saddos tbh, they are stuck in the past and forgetting the present the present where Sonic lost the video game war.
Nope because their rivalry ended around the early 2000's, Nintendo's been holding Sega's hands for years.
They were rivals in the 90's nothing more they aren't eternal.
Sonic nowadays seems lost to me, he was created to counter Mario.
They are eternal Rival as long people argue .
Well so for you Mega-Man fan are stuck in the past ?
Pac-Man fan are stuck in the past ?
Sonic fan are stuck in the past ?
Metroid fan are stuck in the past ?
Mewtwo fan was stuck in the past ?
Starfox fan was stuck in the past ?
Sorry to disapoint you but no . We look foward to the futur , we can't wait to see our heroes come back in the lightstage .
Sonic game aren't worst , there are exeption of course ( Sonic R , Sonic Shuffle , Sth06 , S4EP1 ) actually , if you played them you will see they are more and more good . Sonic Unleashed , Colors , Generations was cool game for speedRun and times attack . Rush series was fun , Sonic the lost world had good mechanic and even had a good port in 3DS . And the Alternate Universe of Sonic Boom look like a simple but cool game for something who was at first a Cartoon Marketing ...
Pac-Man and the Ghostly adventure 1 and 2 games are easy but fun to play , like a Kirby game .
Mega-Man fan are still waiting for a annoncement . But they can at least watch the spiritual son of Megaman : Mighty n9 and Azure Strikers Gunvolt . And have fun with him in Smash .
Metroid still wait for an annoncement ... i can't say much about this ...
Mewtwo fan never lost hope , they waited 12 years for see their favorite character come-back and some people like you was saying " Lel , mewtwo is death and in melee , stap be in the past k ? we need moar character over him . bye " they never lost hope and look now , he's here .
Same goes for Starfox fan .
But like you say , Sonic seems lost for you . it's not everybody who will have the same idea . You can say your opinion but not say to the fan that they are stuck in the past .
