All of the above.

Game does look pretty good. But I dont think its that people are dismissing it, its that most think of Naughty Dog as sony's golden child. Something tells me top guys at sony probably believe that as well and may even throw more marketing behind it. Also with TLOU2, FFVII R and GoT, sony has 3 big games coming this year and maybe gamers and executives are planing of putting competition against Cyberpunk wich seems to be the only other game that might get high praises this last year. Like th fans are choosing a representative. 

Horizon, then God Of War, are my favorites from Sony this gen.

Considering Sony 1st party are all breaking records with some crossing 10+ and 15+ Million sales and keep a steady release of great games during the year by not competing for dates with big 3rd party games.

And they releasing great games at the end of the gen have more likely generated great goodwill and sales than lose sales. The only game that could be argued to have lost sales due to late release would be GT6. But God of War on PS2 sold great and got a remaster on PS3 that also sold good and prompted GoW3 on PS3 that sold well and made a remaster for PS4 that also sold good. TLOU broke the record when the 2 releases are sum.

Sucker Punch have made one of the best looking PS4 game and that was at release. The particles effect, the lightnining and even models on Second Son are just gorgeous, I even liked the story and gameplay as well.

Put that at a setting I love that is feudal Japan with Samurais and they have everything to make me very happy.

Death stranding , the most unique game, (real life). Also shadow of colossus remake (platinum, hard mode and timed,)  is an amazing achievement, propably even more epic than when it first launched on ps2. Both these games are 2 of the most immersives games i've played, along side the original demon's souls. Also days gone should be on there. It's probably the most under rated game. It launched with alof of bugs and glitches, and got hammered by critics, but i jsut played it recently ,  post patch, and the game is amazing in it's own ways. It is the love child of uncharted and the last of us. Borrowed and improved upon game mechanics, influenced sound effects and music, and probably the most satisying zombie shooter adventure survival open world out there. Also dragon quest needs to be on the list, one of the best games ever made. 

There have been a lot great ones, Sadly I cannot put more than 10 on the list. Thinking of changing up the list and keeping the top 3 after a while. 

Death Stranding I liked it although many hated and Days Gone I really liked and didn't had bugs or glitches.

I don't think it's being dismissed either. I think it's more like the HZD effect. Nobody really knows what's coming exactly, and it's hard to tell how good it could be based on what we've seen. Visually it looks amazing, but that's only a portion of what makes a game worthy or worth praise. TLOU2 also has sky high expectations because of the first game, where as GoT is a whole new ball game. I also believe that SNY knows that gamers love a big surprise every now and then, and games like HZD blow up because of this. When a game isn't marketed all that much, and ends up a blockbuster hit, people can't believe it and the game tends to get mega massive praise after the fact. Which SNY also wants, especially with new IP.

Ending the gen with knockout punches just helps to strengthen next gen sales for PS, as long as there are a few new titles on the way for the new hardware. After that, people will turn a blind eye a little bit, if first party games dry up somewhat. Too much drought and then they have a bigger problem though, if that ever comes to pass, but PS seems to be pretty good at laying out a solid game plan for steady enough output.

Second Son was nice to look at no doubt and was a decent title for the initial year launch period. Having the rest of the gen to focus on GoT for PS4 could certainly lead to some amazing results. I'm inclined to think that's more likely to be the case.

Look at the list... I mean... just fantastic. Everybody knows how I love Final Fantasy VII, but just for the big respect I have to all Sony's studios, I voted The Last Of Us Part. 2.

SURPRISE MOTHERFUCKERS!

PlayStation All-Stars Battle II! ANOTHER SURPRISE MOTHER FUCKERS! Half the roster will be from Tear Ring Saga!

That's a deep cut I expect most to not get. Google is your friend.
