Yeah but something Nintendo games seem to lack that most other games have, are difficulty sliders/selections... sure, pop it in easy mode if you're playing with the kids, I totally get that... but why not give us the option for a bit of a challenge too, eh?
Not sure why they don't to be honest. People have been asking the same question about Souls and Sekiro for a long time. I mean it wouldn't be too hard to double damage Luigi hard mode.
For me I like Nintendo's difficulty, but I am at a different place than most. I have played probably 5 hours of LM3 with the kids. Being able to share gaming with the kids is really quite nice. Most companies seem to have abandoned couch coop, luckily Nintendo still has it.
I think my larger point is that raising the difficulty in Nintendo games would be a giant mistake, given a large percent of their audience. A slider would be the better want as opposed to simply making games harder.
