As I recall, the copyright page of the core books don't clearly indicate which version, printing, releases of the core it is. Am I mistaken? Is there an easy way to see, if I find a copy on a gaming store, if it's the latest or not? The UPC, maybe looking at a particular rule and see what it says? For example of that, I could tell 1st and 2nd by how initiative is determined... but what about later editions. On a different but related question: Is there any clear listing of errata from edition to edition? (Edit added: Well, nevermind the errata... While I was thinking of something that listed errata from version to version, the one on the Resources page with it showing the most recent additions is good enough.) Thanks, Liam
