You don't get how someone can be upset that they're not getting content that's already on the disc they paid for?
Ok, are you also upset when some one paid more for the Special Edition and got more stuff? Because double dippers did pay more for the game in the end.
I don't get why people are upset. You got to not pay twice for the game. You get to experience it for the first time in much better quality, with more things than if you just went for the previous gen version (Cause there is some stuff you have access to that wasn't on the previous gen).
All these things you get that people who bought before don't (and yes, I am jealous of those getting to play this for the first time on this version. At the time I didn't think it was a sure fire thing that PS4 would get it so I decided wasn't worth waiting for the chance it was. I would have waited if I had known it was coming to PS4).
Honestly, I think it's nice they are at least throwing those who are double dipping a bone. A bone I might mention that those who aren't could easily circumvent and get the stuff anyways! Go borrow some one's PS3 and copy of the game, play it online for a short bit, register with social club, and voila! Hell, buy an old PS3 off of craigslist, buy a used copy of GTA (I found one for 20 bux with some patience on Ebay after I traded mine and still got too impatient for the PS4 version and that was not shortly before the PS4 version), play it. Then sell the PS3 off (and the game). If it is that upsetting to you, it's not hard to circumvent and still get the bonus's. Or, as other people have said, wait cause most people seem sure this won't stay exclusive.
