Good day all, I was looking at some HQ trailers on the EU eshop and saw that federation forces has a pegi 16 provisional rating, assuming it sticks this would be the second Metroid game to get a 16 rating after Other M (Prime trilogy got a 12). Make of that as you will but this game clearly isn't an attempt to make the series appeal to children, I think it's more of a way to appeal to a japanese audience with wacky minigames, chibi characters and local multiplayer.
On a side note Project Zero Maiden of Black Water will recieve a pegi 18, the only other nintendo published games I can think of like this are the 1st Bayonetta and Geist, also Fire Emblem Fates will still get a pegi 12 even though it got bumped up to 15 in japan and Genei Ibun Roku #FE will get a 16, for comparison Shin Megami Tensei 4 got a 12.
