Excerpt from the review:
"Over the past 9 months Shadow Fall has received a variety of patches and updates, many of which have been free with Guerilla games providing gold-standard support for their title in the form of a consistent supply of free maps. The most recent update however has introduced something the Killzone franchise has not seen before, in the form of online co-operative play. Intercept, the aptly named title of Shadow Fall's co-operative DLC is available in two forms, either as downloadable content for Killzone Shadow Fall, or as a standalone game."

"I personally don’t like the phrase “stand-alone DLC”. Not because of the actual meaning of it, but because I think there’s a negative stigma that surrounds it." -- PlayStation Enthusiast
There's nothing wrong with stand-alone DLC, and nothing negative comes from it.
As the article points out, inFamous: First Light and Uncharted: The Lost Legacy are available on disc too, which emphasises how Sony considers them. I'm sure Horizon Zero Dawn: The Frozen Wilds will be a $40 disc release too.
The Lost Legacy is really pushing the standard though for what is considered as stand-alone DLC. It was just supposed to be a short expansion, and now it's a fully fledged 8-or-so hour game, like the Drake's Fortune. Great stuff.
Left behind is not one of the best games.
Combined with the story of the last of us it is. By itself it lacks the emotional impact and looses the novelty of gameplay changes in comparison to the main game. They belong together.
I could say the same about last light, minus the emotional impact.
All opinion, not fact. No use in getting upset 'cause you may not agree, I'd love to hear how I'm wrong though... In a civil manor.
Uh what? I personally haven't encountered this negative stigma you are referring to.
TLoU is one of my favorite games of all time, but I didn't really like Left Behind that much. I know that's an unpopular opinion, but I dunno, I thought the best thing about TLoU was the Ellie and Joel dynamic, and after playing through the game, and going to a DLC without Joel, just felt like a downgrade to me personally. I didn't think Ellie stood that well on her own. Maybe I'd feel the same way about a Joel solo experience as well, I dunno. There were parts of the game without Ellie and without Joel, but they were part of your goal, whereas there was a complete disconnect with the DLC. I understand that most people love it, and that's great, but just didn't enjoy it that much personally.
Its a nice trend giving single player fans more of what they want plus the value is amazing. You get a full game for dlc price. I'd rather drop 39.99 on an 8 to 10 hour campaign than a few map packs. I just picked up killzone intercept for like 5.99 can't wait to play it. That midyear sale is fantastic! So many good games dirt cheap.

I love digitally downloaded games. There, I said it. They save space on my shelves, save time searching for the game that I want, save me the energy of going to the store, and right now, they save me a bunch of money. Amazon is currently having a sale on digital games for PS4, PS3, PS Vita and Xbox One games, and I’m super stoked about it.

Official PlayStation Blog writes: "Last week, we kicked off the first week of our Holiday Sale on PlayStation Store, and today we enter the second week of the sale. Following today’s PS Store publish, we’re discounting a new line-up of games at up to 60% off, and PS Plus members receive up to 80% off."
Not so happy about the sale this week but I hope at least someone is happy out there.
The best thing for me though is the get $10 credit for adding $60 using paypal!
Trash sale. Maybe, just maybe Blue Estate for PS4 just because it's cheap and titles are few and far between at the moment on new systems. Overall these sales better end with a bang.
