It used to be like $1.99 a month not long ago when I had GP. I completed all the games that caught my interest. Then the price shot up and I cancelled it. I have too many subscriptions in general as it is.
If Sony had a subscription service available on PC I'd be all over it for the exclusives. I'd gladly pay extra for a monthly subscription.
That was always funny because it was easy, free points just to spam the button that either dumped ammo or med packs, but people still wouldn't do it. Heck I'd be at the top of the scoreboard just dropping med packs in BF1.
