The important part is to create a team, people working together, helping each other, trusting each other.
Anything that increase trust and organic collaboration is useful, most of the rest is a waste of time.
Ex: if your estimates are used once to put the blame on someone, congratulation you just destroyed the morale and trust of the whole team. Now everyone will start to lie and pad their estimates, the game is now how to behave to cover your ass and the one of your friends.
