They are not meant to recreate rather than give a greater feel of realism, and I don't D20 does (You're down to to hit points after being hit by a truck and you walk on to regenreate 1d4 hps a day???) I just like my games a realistic as possible to make the player relate more to the character... This is why it's called ROLE-playing. Deadlands Flagship is like a movie, while D20 is like a baaad play.
