I'm not immune to an unsubtle display of the very best tropes one genre has to offer all in one place. I'm especially not immune to it when it's a genre I love. So that's why I'm writing this: Because the trailer for Mecharashi is exactly what I want from a mech game trailer and I like it a lot.
There's haunting music, which is good because the idea of building-sized fighting machines battering each other in an already-ruined landscape is haunting. There's a lovely shot of a beautiful detailed technical-looking machine interface getting flipped on. There's machine guns in both hands of a giant robot, and a giant robot with a shield. There's an absolutely wrecked mecha missing an arm getting back up for just one more round of fighting. There's even the not-so-subtle implication among several shots that this entire experience is both very traumatic and very exciting for the pilots.
