Class Shooting 2015

So many classes, so many characters

I just saw the video for Overwatch and it got me thinking about Class Shooters and their rise in 2015.  This and Battleborn are both coming next year-ish and are equally PVP Class shooters that run with different characters.  But I find there's little separating them from each other apart from IP and some execution, which I wager will filter out into being equal in the end, short of some brand new game type they have secretly in the works.

Then again, what's the difference between these and Team Fortress 2?  Again, another PVP Class Shooter, each class with as much character as the last.

I'll admit, I'm not a big fan of PVP catered games.  Sure, they're fun for a little while but eventually I just end up having my arse handed to me over and over.  I do prefer a more cooperative environment, coordinating attacks against waves or arrangements of enemies.

In saying that, Evolve looks really fun.  Four players versus either an AI of a monster, or another Player of a Monster.  The Four players hunt down the monster, who starts off exceptionally weak and evolves into something that can possibly pick off a single player, and then evolves again to be able to take on all players at once.

Does PVP draw away from IP though?  Sure, you can have a background of characters and setting, even environments, but do they end up more than just a blurb that 25% of players may actually read?  Or will there be a story for those characters to play through?  Something that really brings them together more than just a mercenary contract coincidentally in the same spot, or mutual drive for survival?

And more importantly, will this change what games will come out next year?
