hep-th/9312054 | W-Strings from Affine Lie Algebras | The most disappointing aspect of $\W$-strings is probably the fact that at
least for the known models one does not recover a physical spectrum that
differs much from that of ordinary string theory. It is hoped that this is not
an intrinsic shortcoming of $\W$-string theory, but rather that it is a
