Joints question for a multiplayer game

Hello guys I was wondering some questions. We are developing a multiplayer game with a 5 vs 5 players; and we would like to know how many joints is the best option for the skeleton. Thanks!

You should create your skeleton to fit your needs of the game.
Do you need individual fingers? Do you need hair movement, eyes that move?
The more joints/bones in a skeleton the more articulate it can be, so really the answer to your question can only be answered by you and your team!
