Hands down one of the most over rated characters and game series ever made; but I fully understand why people would consider him a mascot and look back fondly on his games.
Crash Bandicoot was a poor mans Mario. Released on a console back in, what, 1996? In terms of quality in games he was up there with Bubsy the Bobcat, Cool Spot, Sypro the Dragon, Croc and x-amount of other characters created back in the nineties.
Games that were no where near on the same level as Mario in anyway shape or form.
I had this argument the other day. Crash Bandicoot hasn't been relevant since the PS1, but, the reason why people still harp on about him is because he came about in a new generation, not only of consoles, but also a new generation of kids, kids born in the 90's and maybe even early 00's. These kids owned PS1's, with maybe a few owning an N64 and Sega Saturn as well. If anyone of those kids says to me that they preferred Crash Bandicoot over Mario, Banjo and Kazooie and even bloody Rayman and Sonic then I'd say they were nuts or blinded by nostalgia.
Crash Bandicoot games are mediocre at best and I wouldn't even class them as platform games as there is very little need of any platforming skill at all.
Yes he was a "mascot" back then, but there's a reason why he's been left in the dust, the same reason why we don't see Bubsy the Bobcat, Cool Spot, Zool, Croc or anyone else; they were characters of their era attached to mediocre games.
But, if Crash Bandicoot did return and Playstation players raved about it, then those players should be open to playing fair superior platform games on other systems. We'll see anyway. 40 million PS4 players out there, let's see how much Ratchet and Clank (another mediocre series) sells for as that should give us an indication on how much a new Crash Bandicoot would sell.
