Mort: I'm all for crazy/whacky, but It's easier to adopt some of the preset rules if we want this thing to remain consistent. Otherwise, one games rules may differ from anothers, as different people will be hosting. However, consistency doesn't matter much, and maybe one person can host them all, or some custom rules settings can be made and shared?
It doesn't particularly matter, I guess.
Oh, and I'm not familiar with the points for weapons option, but it sounds good. I absolutely refuse crazy mode 2 though, due to the simple matter that I am incredibly bad at it.
Alternatively, Teams? Knockout? Some idiotic and pointless league-type system?
