I never did get a yes or no on a character who can create perfect duplicates of himself. That alright or am I barking up the wrong tree?
My apologies. I completely missed it!
Duplication. My initial reaction was "Nope, no way, never, nix nein Frankenstein." But I had a recent conversation with my son about learning to self-examine when one has a strong negative to something, so...
After some thought, here's my problem with duplication: it allows one player multiple actions in a turn/phase/whatever. This is in turn allows that player to have far more impact on a scene than other players. It also greatly increases the size of a team, which can cause problems in game-planning and combat management. It can cause problems outside of combat, too, where Duplicate A goes to watch the warehouse while Dup B hits the library to research the thing, Dup C questions the witness, Dup D asks the scientist about the villain's power, etc. etc, while the rest of the team sits on their collective thumbs.
In short, it can destroy game balance.
I don't know how to construct a duplicating power that doesn't have that effect. If you have any ideas, let me know.
