A lot has changed since beta. This game gets monthly patches to add in new content. I wasn't in beta, but just recently, after that progen Khan guy came back and declared war on the V'rix (those weird spider looking ships), the V'rix invaded and destroyed the Progen main base on Planet Primus. The story line has gotten rolling and its very interesting and captivative. I haven't played any other online RPGs, but i believe Earth and Beyond to be one of the few thats changing so quickly and has such a progessive storyline.
