If they had just called it Galactic Federation Force, and shown the same footage people wouldn't have given it much of a reaction.
If they had done that, and at the end of the trailer shown something/someone from Metroid as a teaser, or otherwise had the fact that it was in the Metroid universe as a big reveal, then they might have even had a positive reaction.
This would mean that people would be getting sold purely on the merits of the new game and have the surprise as a bonus.
Instead we have a game that is up front and center about it being a Metroid game without Samus, and that if we aren't okay with that, then we should just play the game and we'll get over it.
So, by playing a game that has little to do with the series its being sold under and which feature gameplay I don't think I'll care for as well as an art style reminiscent of Spyro in Space I'll somehow be won over? Also, that you are making the game under fan protest, which you expected? And I'll totally forget that you have already admitted that there are zero plans of making a Metroid 5 in the next several years?
I guess we had all better shut up and buy this game if we ever want more Metroid by 2020.
Meanwhile games like Shantae, Shovel Knight, Bloodstained, Axiom Verge etc. are just gonna keep fruitlessly putting out Metroid-Style games that there just isn't a market for...
What's that? Each of those games has been hugely successful (some anyways) and people are throwing their money at them left and right?
I guess we should tell Nintendo about that.
I'll admit that its fun to jump in with the hate mob for this game, and when they admit they expected it its kinda too easy.
They did some fun things with Hyrule Warriors. Maybe next they will do a Dark Souls style Zelda game...
Admit it, you want that.
