You've obviously never done a fight scene with me before...oh wait...yeah you have. =OP Anyway, I do want a system of some sort so that one person can't get too attached to their character and say hey I don't want that to happen...so it doesn't! Ha!
Ahem, anyway, I also want to avoid autohits, and god moding and all that jazz so systems pretty much take that out of it. I don't agree with planning out a fight before hand and seeing who wins, mostly because there are no surprises in that, nothing can happen in the middle of the fight to turn the tables... You get the point, I just don't like planning out a scene too much before it happens. Now if someone said, okay my character is on this rooftop if someone wants to happen to have their character nearby...that's about as far as I'm willing to go on the whole planning thing.
Anyway, ultimately it's up to Lord Anubis, since he knows how systems work way more than me. I know all of one system...and that's only half knowing it. ^^ And it was made up by someone on Shards, so most people on other sites don't know of it.
