As the guy that posted the video and pics in the original post, I feel a little obliged to post in here.
Press kits, on the whole, are *insanely* few and far between. 99 times out of 100 we'll get a game to review either as a download code or a promo disc (plain jewel case, red and white disc). That other one time though will be something a little more unique. Aside from Sony, the only press kits that I've seen for our site was Alien Isolation and Dark Souls 3. Oh, and we got a Lego Iron Man minifig for the Lego Avengers game.
In terms of "big things" this year, we've also received press kits for Uncharted 4, No Man's Sky, as well as a PS4 Pro and a PSVR Headset. We've also been totally up front about receiving them from Sony, and if people want to claim we're bumping scores up because of it, then so be it. We didn't actually score any of the hardware we've received this year, but it's allowed us to compete with "some of the big boys" on that front. I've made sure that everything we've received for the site is open and transparent, be it a press kit, a free piece of hardware, or a review copy.
Regarding why press kits exist, I dunno. It's mostly going to be sat on a shelf in an office somewhere. But ultimately, if a game is shit, I know I'm going to tell someone that it's shit. The "Press kits are just bribes to get good scores" argument is ridiculous IMHO. Anyone who gives a game a higher score because they got a feather and a couple of art cards in a package isn't really worthy of giving a game a score.
If people deem my review "wrong" because we got a press kit, then so be it. I got an Uncharted 4 one, I also gave that game 10/10. I'd have given it 10/10 if I'd needed to go and buy it on launch day. We got Titanfall 2 a day before the embargo, and our review went up after release. It's one of my games of the year and it got a 9/10 from me. Would that score have changed if we'd gotten it a week earlier and with a fancy box? No. I review the *games*, not the boxes they come in.
Oh, any stuff that we do get is usually prefaced with an agreement that it's for coverage only, and can't be lent or sold. Not only is selling it breaching that, but it's scummy as fuck and I'd never consider it.
