I can't wait till the real series come out but for now the small snippets of trailer are enough, They give a lot of indepth focus on what the series is gonna be about, which is of course the Infamous Stridsvagn!
Knowing the creator I belive these are one of the greatest trailers I have seen in my life time, It makes me very excited to think I might be able to one day watch them, crying, laughing, and become smarter from the plot that resolves around the Stridsvagn, The idea behind it is so great I would put the plot and lore behind all of this at the same spot with the Anime, Attack on Titan and Death note.
For now, I will give it a big 10/10, maybe that will change when the real series comes out, but I doubt so ;).
