Tzuppy:
Name seems familiar, but I don't know where from. What is it?
I haven't read the background carefully yet (it's surprisingly extensive), but basically, every Godzilla-style monster (Kaiju) movie is "real" -- Earth has been under assault since like the 1950s, and a defense force has been implemented: giant mecha / robots. Think Pacific Rim. (In fact, if I end up not liking the background, I might roll with Pacific Rim as a setting instead. I love the international angle, if not needing two pilots for each machine.)
It's pretty anime-influenced, as well, in terms of the character archetypes presented (tough guy/gal, Hero, Cute Guy/Gal, Rebel, etc.), and there's a neat element where there's a group (the Ninja, I think) who worship the Kaiju -- and they actively work against the Mecha Assault Force.
I'll post more once I give it a good read.
