ideally I think the MFL was just something new and different... sure there were always Fighting RP's and mech RP's (gundam)... but nothing for Big O and all the crazy Memory-driven mumbojumbo that went on in association.
That's why I liked it. Could create your own megadeus in a show that had amazingly crazy designs... and of course count on some sort of random dramatic dialogue between characters that hinted at deeper plots that never ever got fleshed out (until they did, and the world died...twice). I really loved that RP... and I don't care much for other RPs. Good times before the world ended. (even then I like how
I ended it

muahahahaa)
