Well, after some consideration I've decided to simply add some of the rules of FFO to my ATZ:BDTZ game instead of importing over wholesale. There's just too many new things I'm unsure about. Oh I like the explanation mode of FFO (as I noted in my review) but most of that I've finally figured out from the THW yahoo group and the Board of the Living Lead.
So, I'm importing the FFO campaign rules, Star Power*, Zombie rules, and firearms systems. I'm also going to use the increased attributes and talents. I might add more as play progresses but most everything else in FFO either seems too clunky or apples to oranges; a different way of doing XYZ but not IMO better. At least, it doesn't seem better from a read-thru. I might feel differently in play.
Oh, and Game 5 (last full ATZ:BDTZ) game will be up in about a week with pics and such. No, really! ;)
