User blog:WaterKirby1994/Nintendo, Sonic's Savior or Demise?

Ok this has been a question, I'm curious how the fans here all view Nintendo? I know that Sonic was created for the sole purpose of competing with Nintendo back in the day. Sonic Games are what sold the Genesis so that it could compete against the SNES. The entry of Sony & Microsoft to the Console Wars combined with the flop of the Sega Saturn in the States, it's understandable why Sega left the console market right?

The Partnership of Sega & Nintendo resulted in Sonic Adventure 2 Battle being a best seller on the Gamecube. Games were produced like Mega Collection & Gems Collection to increase Sonic's fanbase & give the new fans means to enjoy Sonic's past. Tons of good came out of Sega partnering with Nintendo right? There's some belief that without the need to compete with Mario, the quality of Sonic games dropped severely, or that Nintendo is to blame for Sonic's downfall? I don't think that's the case & want to ask the community their thoughts on the matter.
