I would put this in off-topic to better ask that community, but this is a gaming thread, so #gaming it is.
For me, it's Destiny.
Does it have a nauseatingly repetitious macroscopic gameplay loop with very little in the way of tangible rewards for a pseudo-RPG and what meagre story there is in-game is badly delivered through half-hearted loading screen dialogue and a handful of cutscenes? Yes.
But it also features some of the most polished and satisfying gunplay of the half-decade, with enjoyable RPG elements besides the broken rewards system, and Bungie's ever-masterful world building and design. I love it, and I have barely stopped playing it since (a week after*) launch.
Honourable mentions? Watch Dogs, TLoU Remastered, Child of Light. Sunset Overdrive could be up there too, judging by that free weekend on which I tried it a few weeks back.
*I was away that week.

In order: Super Time Force, Destiny, then Child of Light. I would say Limbo too, but that is a remake. Honorable mentions are Watch Dogs, Ryse (Unless that released 2013), Valiant Hearts. I would list TLOU as an honorable mention, but it released last year.
