There's a good opinion piece here that I largely agree with (hence it being good, obviously). An interesting fact I didn't know is that one of Nintendo's pre-videogame products was a line of folding paper models, so this is kinda coming full circle for them.
I'm just trying to think how 12 year old me would react to this. I don't think 12 year old me would be that thrilled to see this. Looks like it'll break after only a few uses. How much will a replacement cost?
I love the concept but like a lot of people already said, its fragility really buts me off buying it. Even if its something that will mainly be bought by grownups i doubt that cardboard will last that long in any case. If they did the same thing with plastic i would be more interested.
