The American one was supposed to be a showpiece mostly, while the Japanese one was a tech demonstrator. Then they both added paintball guns, and things slowly spiraled out of hand and into AWESOME. The best part has to be one translated shitpost from Japan:
Sasuga Americans.
Challenge aside, I just want to say one thing. What the heck, Japan.
The natural order of things was for gigantic robots in Japan duking it out with one another, and the champion gets to go to the US for a challenge...
I've been waiting for it for four years since making the Kuratas, and see where that's gotten us.
Very much upset.
Just hold on Megabot, I'm gonna think of something.
On the plus side, though, this stuff is sport-only. The makers of both have openly admited they're not looking for military contracts or anything, just a good, clean, GIANT ROBOT DUEL. So far, the only things we know about the match rules are that one, safety has to be maintained, and two, the winner has to be the one that can leave the ring under it's own power.
