Diablo III. First time I played it was at the urging of my friend, who told me unironically, "don't worry about the plot, the plot doesn't matter." Unsurprisingly my experience wasn't particularly engaging and I lost interest, not seeing much reason to play it over any number of other games that didn't have an always-online requirement.
Flash forward several years later. My then-girlfriend (now spouse) asked me if I'd ever played a Diablo game, and I related my experience. After she was done sputtering and emitting various noises of extreme outrage she insisted that I set things up so we could play through Diablo 1, 2, and then 3 together. I went in to D1 expecting to be similarly disappointed and instead found an incredibly dark, atmospheric, and compelling story. Oh and we did get The Butcher so I also shat myself. After that I was way hyped for 2, and by the time we hit 3 I was far more interested in playing. Loved the hell out of it, found myself not only enjoying the game but completing through the last stages of a season journey to score extra stash space and all that. Not out of obligation either, I was legitimately enjoying the grind.
