For me it's less about the actual games, or how the specific announcements were done, but more about what Square-Enix said. It really feels like the "good old days" are coming back and many people definitely feel the same. There is a bigger support for and faith in these projects from the relevant parties now than in a looong time.
After years and years of everyone totally ignoring that part of the audience, taking absolutely zero risks and many japanese developers comletely changing or disappearing, it now seems like so many of them are coming back! Even if you personally don't care for it at all, you have to be able to see, objectively, why this would be such a huge thing for people. Can we just be happy for video games as a whole for this week at least?
I guess people are preparing themselves for waiting a very long time for these newly announced games I suppose :l. While it is amazing to have the three 'Dream' games being announce back to back to back, they took a very long time to become a reality and the other two 'Dream' games of FFXV and KH3 are taking a while to make (though FFXV should release sometime next year hopefully, with KH3 not long after ). Point is, these games take a while to make and people are being cynical to prepare for the long wait for these tittles.
But, I don't think they will be taking that long to become a final product. Going through everything, we have the following:
-FFXV re-started development around 2012 and as of right now, the game is 60-70% complete with a demo in the hands of gamers on PS4 and X1. Many expect this to come out sometime next year.
-KH3 got announced in 2013, with two gameplay demos being shown off across both TGS 2013 and this years E3. Between switching to UE4 and having a team with singular focus (no more remasters or ports), the game should be on track for a release sometime either late 2016 or early 2017 .
-Last Guardian is fully explained; the game got moved to the PS4 due to hardware constraints in the PS3 build and after completion of Puppeteer, Gravity Rush, Rain and Knack, Studio Japan got back into focusing development on the project and if Sony is correct, the game will come out 2016.
-Shenmue 3 just got announced and after getting fully funded from both Kickstarter at 2 million and Sony stating that they will be funding the rest of the game, the development can fully start now. The Kickstarter states it will be 'delivered' in 2017 but it would be safe to assume that it will be coming in 2018.
-FFVII Remake has been in the works for at least a year if rumors are correct, so development of the project has some progress done on it. I believe this will come to us a lot faster then we are expecting; this is a HUGE game for not just Square Enix but to Sony as well; both parties will be very aggressive in getting the game out the door as fast as they can in a big push in reviving the PS4 in Japan. I expect this to launch in 2017 after KH3 comes out and it to have a demo shown off at TGS this year .
Those 'dream' games are real and have firm roots in reality. They are coming and they will be a lot sooner then we are all expecting. Its fantastic to be a gamer this week, as hope is back man !
