I'm 27, been around the days of classic Sonic, and can utterly agree with Mr Sterling.
However...
When I see my not-yet-in-highschool nieces and nephews playing Sonic Boom and having a gay ole time, unable to shut up about it during sleep-overs or even when we pick them up at school, then I end up wondering if our bitching of our beloved franchise even matters anymore.
Considering it's a game for children, what with all the bright colours, saturday morning cartoon dialogs, and a mythology that's as deep as a cereal box, I don't think we adults (young and old) should care anymore.
Mr Sterling basically says that Sega has been doing the wrong thing, how it needs to be the same good ole stuff, just improved slightly and polished. And I'm sure that method would please the ENTIRE fan-base.
However, if Sega's goal is -
1. Make a children's game.
2. It must feature Sonic.
3. Be enjoyable enough to engage children.
Then I think for all intent and purposes, Sega was successful.
And NOW whenever I see a YouTube personality or a game reviewist shitting all over Sonic Boom, I can't help but see a fully grown adult telling the world how he or she didn't enjoy themselves when they were playing with a kid's toy.
