Naughty Dog has grown as developers. Insomiac never lost talent, they just tried creating a Halo killer. The thing is people like Halo for a reason. Resistance turned out to be a good solid series so they didnt fail as developers, they just failed at what they set out to do. Ratchet and Clank are great mascots and has good gameplay mechanics but they are going to get smaller as time goes on. If they were on a nintendo platform then they would probably gain popularity. While this is sad it is true. This goes to jak and daxter too. Great games but if they make a 4th it will not be as successful as the previous 3. Sly Cooper same. The thing is that these type of mascots are no longer big like they were in previous generations. The only place that these type of mascots do good in are on nintendo platforms. Now this doesn't mean they wont be successful because they will be. They will all be able to sell more than 1 million maybe 2 but not more.
