Diablo 2. I was still in school, parents had dial up, and it was marketed in such a way that I thought it was mostly catering towards the online experience, so I blew it off. Flash forward nearly 20 years, get into D2:R, single player is actually pretty cool
It’d be nice for there to be ‘halo software’ to raise market share, otherwise I think it’s circling the drain, suffering from the same feedback loop as SLI. It’s niche, so developers aren’t exactly clamoring to port things or make new offerings for it, which leaves consumers with less incentive to buy the hardware, which leaves developers with even less reason to touch it. Would Nintendo be in the console business if not for Zelda, Mario, and Tetris? Hard to tell
