For a game the reseeding in my post is certainly enough.

/dev/random usually contains really good random numbers, but reading it could block your scripts by seconds or even minutes if the machine is low on entropy.

/dev/urandom is much faster, but contains less "real" entropy. So /dev/urandom or the last state from rand before setting the seed should be OK.
