Well, if you feel, even as one of the most optimistic admirers of the game, that it will only manage to gather a niche audience, possibly just enough to keep it alive, then it's pretty much a failure, no? This is a reputed massive studio with a massive budget and dev cycle, not to mention ludicrous levels of influence and autonomy enough even to influence projects of top-tier devs such as Naughty Dog. If, after all that, they can only manage to attract a niche audience, then well...
I was a massive Bungie fan and to see their fall from Reach, etc, to this.....they could have done much better....they should have done much better. A next-gen exclusive AAA title from a flagship Sony studio shouldn't look low detail and budget compared to something like overwatch 1.
