This sums it up a lot of it. As games built on successful commercial models give us more and more, it's interesting to turn back the clock to a time when the hobby was a hobby. But instead of a purely nostalgic experience I have thirty years of gaming experience to bring to my re-examination.To me the Old School Renaissance is not about playing a particular set of rules in a particular way, the dungeon crawl. It is about going back to the roots of our hobby and seeing what we could do differently. - Author, Bat in the Attic
One of the things I am enjoying about Adventurer, Conqueror, King is that it is not just a retro-clone, it's a game that starts as a clone but adds a simple proficiency system, and a complete domain system, becoming much more than a reprint of BD&D+.
