I can't say I was ever a huge fan of the Action Table rules or of any of the myriad of other similar rulesets that were everywhere during the mid-1980s. But, even so, I'm glad to see it revived for much the same reason that I'm glad to see Basic Roleplaying and other non-D&D-derived systems revived. As Dan Proctor rightly says in his foreword to Rotworld:
"old-school" occupies a lot of breadth, and other genres and systems should also be embraced. One of the great things about the 1980's was the proliferation of so many game systems and genres attached to them. Some of the games were more generic in genre, some were idiosyncratic and quirky. But all of them offered us a menu of options we could turn to when we were looking for something a little different. That's part of my mission as a publisher. I want to provide a menu of options.I think that's both true and extremely well-said. Unlike some commentators, I think it's not only natural but healthy to see lots of new old school RPGs appear, each one a reflection of the unique vision -- and quirks -- of its creator. Mind you, I'm also not a big fan of either "universal" systems or the unmodified re-use of the same game system again and again, so clearly I'm weird. Regardless, take a look at Rotworld or some other RPG that has its own unique system and revel in its uniqueness. For a lot of us, that's a big part of what "old school" is all about.
