Holy shit. That's more than any main Sonic game. Crash is much bigger than people give it credit for.
No, Crash was much bigger than we give it credit for. The series was super popular 15 years ago, but it's only been a shadow of its former self ever since. Children don't even know anymore who Crash is supposed to be and his remaining popularity is limited to the nostalgic 20-somethings.
That doesn't mean that a great Crash game couldn't become popular again, but its former glory is just that: a thing of the past. It would be really cool if Sony went back to the IP, but looking at the current market, I can't imagine them giving it the treatment it would deserve. Mascot plattformers just aren't popular these days.
Well, if they aren't called Mario something-something or to a much lesser degree Sonic-whatever.
