Ok,  I'll revise my statement:

Just goes on to show that all indie devs who have a good game on their gands should put those games on PS+.

I think by giving it for free to PS+ user had create the hype and the success the game had today!
So by thx to Sony for that.

Depending on how much money Sony gave them, it may or may not have been a good deal. The game was good, there was already hype for it on PC. It would have been received well and sold at least a million or so on PC. The big question is how many PS4 owners would have bought it instead of getting it "free" with PS+.

those 2.7million copies didn't sell day 1 you know

but there were hundreds of thousends > millions of PS+ users playing the game online from day/week 1

Everyone I know that has this game, bought it because someone else recammended it to them by word of mouth.

If thats because it was on PS+, then that was worth it, even if all those downloads didnt give them huge pay days.
It help build a fanbase, and the word of mouth has since effected sales, and will continue to do so.

Not surprised, got it for free on PS+, I imagine it was one of the most downloaded PS+ titles as well due to the hype from the psn beta.

Also damn, 7 million on PS4?

6 million PS+

1.3 million sales

Is Xbone included?

It's actually over 7.4m on ps4! 

well this just prooved how bad the pc plattform is, if it only sells double as many copies on pc compared to ps4, where people got the game for free.

Without PS+ this game would have been nothing

Great sales for this game, it was definitely a surprise hit this gen!
