IMHO, I feel that the Walking Dead, Metallica and Star Trek have very similar layouts. One of the reasons I sold my Walking Dead was I felt it was too similar to Metallica.
Theme wise Star Trek should have won hands down. But Sterns lack of communication about code, pused me to Walking Dead instead. When I got to Walking Dead I liked the layout but the code was a little weak and no actor call outs. Then I got Metallica, polished code, a few xtra shots and the Sparky bash toy blew away thr zombie in the barn so TWD left.
