I hate to be that guy, but isn’t it about time to put Knack to bed? I was shocked to see that they even bothered to make a second game, but they seem hell-bent on turning it into a franchise.
Sony is pretty smart with its various franchises and how it spaces them out. I've never felt overwhelmed by any Sony property (except maybe Ratchet and Clank, but that has now been on a long break). Sony really doesn't have any franchises suffering fatigue right now. The closest would be Uncharted, but it also seems like Naughty Dog has put that one to bed themselves, at least for the time being. Remember that The Lost Legacy was simply expanded from what was originally DLC for Uncharted 4, so Naughty Dog technically still did plan for Uncharted 4 to be the big conclusion. More often it's yearly franchises like Ubisoft's Assassin's Creedthat begin to suffer and need to go on a break, and look what happened with Origins once it did!
In fact, I think the time is nigh for more Sony franchises that are returning from breaks than any notable ones that need to be put to bed. Just look at the likes of God of War, emerging from the slumbering cocoon as a different and evolved beast after a long winter's nap.
I really have to say Uncharted needs a break. While they're consistently well recieved games, it just seems like Naughty Dog needs the chance to work on other games. Yes, they are working on The Last of Us Part II, but the developer seems stuck in this particular niche and it'd be nice to see them return to their roots.
Uncharted, for sure. I firmly believe the series still has a future, but with Naughty Dog said to be mulling over ideas for a new IP beyond The Last of Us, it'd almost be a sin to restrict such a talented studio to only two PlayStation franchises.
Naughty Dog has already hinted that Uncharted's going to take a rest - temporary or permanent, we don't know yet. Nathan's story is definitely done, but I think they might want to explore other characters or some sort of spin-off. But knowing Naughty Dog, I don't think we'll see that any time soon. What I am worried about, however, is God of War. Ascension was fun but didn't stand out in any way. If the upcoming title (which seems to be trying a different formula) doesn't work out, then it's time to let it go.
