I don't play video games enough anymore to know whether this is widely acknowledged, but the growing popularity of NewGame+ modes strikes me as really clever design, when you embrace it in full. 

You get to build an accessible experience for most normal players, and sidestep the usual ego problem. i.e. a large amount of men will only pick the highest available difficulty, much like they will only pick the largest size condoms, so if you truly make maximum maximum, then it's unbalanced for the majority (of males anyway; no idea if the pattern repeats for women, that would be interesting to find out).

But as NG+ only starts after the first run is done, no such problem. The casual ego players are gone by then, satisfied with their "max" run1. The remainder is here for the gameplay loop, and (ideally) gets to enjoy an increasingly finetuned experience.

NewGame+ modes really do add an interesting layer to gameplay design! They provide a fresh challenge for experienced players without overwhelming newcomers. It's a smart way to cater to different skill levels and keep everyone engaged throughout the gaming experience. Love to see how this trend continues to evolve in the gaming industry!
