Call me "old school" but I like the rulebooks of old. No "useless" industrial mechs, not much "fluff" and not so many options that it takes an hour to come up with a decent mech of your own deslgn. I stopped buying books after Master Rules revised came out. I downloaded an earlier "Total Warfare" , but didn't like a lot of the rules changes, (like partial cover, plasma weapons, airships (really?) and the like. I have the revised mech sheets book (from the MR revised), but none of the video game inspired stuff.
