Let us consider the following excerpt from Mahabharata
"He also beheld the princess of Pancala, decked in garlands of lotuses. Having attained to Heaven, she was sitting there, endued with a form possessed of solar splendour. King Yudhishthira suddenly wished to question her. Then the illustrious Indra, the chief of the gods, spoke to him, ‘This one is Sree herself. It was for your sake that she took birth, as the daughter of Drupada, among human beings, issuing not from any mother’s womb, O Yudhishthira, endued with agreeable perfume and capable of delighting the whole world. For your pleasure, she was created by the wielder of the trident. She was born in the race of Drupada and was enjoyed by you all. These five highly blessed Gandharvas endued with the effulgence of fire, and possessed of great energy, were, O king, the sons of Draupadi and yourself.
From that, it is clear that the Draupadi is Laskhmi itself in Dvapara like Sita in Treta yuga. Sita is well worshipped and Draupadi is hardly worshipped. Is there any reason behind this?
