Where do I start? I've been playing D&D since 1983, and my kids have started to ask about playing, and after a few lackluster sessions with other OSR rulesets, this one seems to have stuck. My players (old and young) like the diversity that's been built into this game, along with the tweaks to some common rules, and just the layout and way this is presented, and it's like a breath of fresh air for my kids, and my gaming crew.
I've seen some of the stupid negative comments here and there about the inclusive nature of this game, and seriously, don't let that detract from what this is - a great OSR option that's been thoughtfully compiled and with some nice tweaks added for good measure.
I was a kickstarter backer, and I got the hardcover printed rules and pdf. The print copy was great quality, the binding seems very sturdy, and the content is well-organized and with some great OSR-inspired art.
There's enough new stuff here to make this worth the purchase. It's a fresh take with enough "old bones" underneath to make it fun and workable.
