source Seems like rather similar options to me?
But I have to admit to never having used either anyway.

there is an estimation i saw about the development cost of Breath of the Wild, at somewhere between 80 and 120 million USD. Breath of the Wild was 4 years in Development, Tears of the Kingdom spent 6 years in Development.
above 120 million for Tears of the Kingdom doesn’t seem unreasonable.

Mario Movie was 100 Million.

Anyway, both are stupidly profitable for Nintendo

How does crossplay in shooters work?
are controllers genuinely competetive to mouse and keyboard?

Remnant 2 seems to be cooperative? So at worst console / controller players are less of a help?

As of August 6, 2023, The Super Mario Bros. Movie has grossed $574.2 million in the United States and Canada, and $779.3 million in other territories, for a worldwide total of $1.355 billion.

[Tears of the Kingdom] sold more than 10 million copies in its first three days of release, and had sold over 18.5 million copies by June 2023.

at 69.99 a game, would mean the total volume sold is roughly $1.295 billion, 60 million less than the Super Mario Movie.

I’m not certain if the movie gross is the same calculation though. It seems that the calculation is fair But data for Tears of the Kingdom is about a month older so that it seems possible it passed The Super Mario Movie by now.

watch astartes (warhammer 40k)

yeah, it doesn’t destroy anything on the worldwide scale.
but it weakens.

erosion is a rather perfect term for it

well it feels like Prusa doesn’t like to give too much information until they sell the product.
with them open sourcing the designs, it kinda makes sense that they’d want to keep as much headstart as possible
