I think FFVIIR had the largest reaction of all time, not just the Decade, but the history of gaming. It is the most justified hype of all too. Factors are:
1. The decades in waiting, the trolls on previous ports/remasters, even PS3 tech demo of it
2. Both fans which could understand, and who could not understand the reason SE would make the remake unified at that moment
3. It is one of the most needed remakes, the game aged, and many fans couldn't relay the FFVII experience to their younger peers
4. It is generally known as one of the best games ever made, and one of the most influential for even developers themselves
Honorable mentions are Starcraft 2, Resident Evil 2 Remake, Shenmue III, Red faction Guerilla, and Death Stranding
P.S. I don't understand the Super Smash hype so much, as Mario games iterate on each Nintendo Console, I'll be shocked if there's a Nintendo console without a Kart/Smash/Mario platformer. I'm actually surprised Mario Galaxy 3 hasn't come out yet :)
