Some folks in this forum and others think they must own every game ever that is released.
I pretty much stick to genres I'm interested in, and do my homework. I make sure that even if the game is in a genre I like, that the games art design and gameplay mechanics are my cup of tea. It really isn't that hard to avoid hype. I definitely get excited for games, but it's my own excitement, not feedin off of the hype of others.
I think the last game I did that with was one of the Atelier games, because the Vita thread was going on and on about it. Bought it on sale, installed it, played for about two hours and was like, "Hmmm," not feeling this." I also bought Stein's Gate off of a recommendation from a trusted friend, and I played three or four chapters before uninstalling it. And I like visual novels! I just couldn't get into it.
Not every game is going to be for everyone, even if a large portion of the community is going apeshit over it. I like to make up my own mind about a game, and no longer buy them because of reviews or hype.
I bought Watch Dogs because it looked cool, but it bored me to death after about 10 hours. I bought the Order 1886 because it looked cool, and I loved it. Sometimes you won't know what you're into until you play it. I grew up in a generation where you just kind of hoped for the best. I still own Friday the 13th on the NES as a reminder, so I never forget my shame.
I've loved bad games, and disliked good games. I've hated bad games, and loved good games. At least I made those choices for me, and not the hype train. My wallet has cried a few times, though (fuck you, Tomb Raider: Angel of Darkness and Legacy of Kain: Blood Omen 2!).
Oh, and I LOVE No Man's Sky, since this is a stealth NMS thread. Once I beat Dark Souls 3 and play some Deux Ex I'll get back to it. I've sunk at least 30-40 hours into NMS so far and it's really addictive. The sheen will wear off eventually, but it's been a good, if jank time.
