I wasn't able to watch, though I'm kind of glad I missed it. I'd have been really underwhelmed. Horizon is THE GAME that was going to get me into a PS4. With it delayed, that means I don't even have to consider a purchase until 2017, and if they follow MS with a new console then, I might as well wait for that as well, meaning I'll be backed up into late-2017 before I consider a Sony console.
Detroit: Become Human seems cool from a conceptual standpoint, more than anything. It's like an intro to building AI or something, and I like that thought. However, I worry about if it'll interest me as a game.
I still don't get the interest in The Last Guardian. Last year's reveal did absolutely nothing for me. I'll have to see the footage from this year, but I don't expect it'll change my opinion.
Crash remastered disappoints me. If you're going to do that, do it with a new game in-mind, IMO. The only time I find myself wanting a remastered series is if something new in that series comes out and I want to see the previous content, which leads me to...
I'd be interested in God of War, but I'm not. I've never played the games before (minus an hour or two of the first on PS2). Without the rest of the story, I just don't have interest in jumping into that franchise. That they ONLY remastered God of War 3 for PS4 was really lame. My cousin felt the same, as he got a PS4 and considered getting God of War remastered, until he saw it was only the third one. On the flip side of that, I'm glad they redid Uncharted, because I might play the remasters of that someday.
Overall, the main game I wanted is delayed, and there's another that intrigues me. Not too much from Sony for me to get excited about. Horizon and The Show remain the driving interests for me, kind of sad that they couldn't get me interested in anything else over the past year, though Detroit might do that.
