"To play, one needs to draw a card."

Translation: Pour jouer, il faut tirer une carte.

[d10MplTj]

Why not "on a besoin de...."?

[bibsoconner]

I have the same question. Why not "on a besoin.." When is "besoin" used?

[5004cupcake]

Me also.

[La_Mariette]

I think "a besoin de" indicates an emotional need, a desire.

Is pulling a card the only/normal way to say this?

[Ripcurlgirl]

Tirer is the common verb used to mean "draw", as in a card, a curtain, even a bow to shoot an arrow, yes.
