This is my favorite OSR tabletop RPG. If you love old school D&D, this game is basically a cleaned up and modernized version, with all the positives of old school gaming, plus all the benefits of modern mechanics and amenities we've learned since then. The large and active community is another wonderful selling point, with all the answers you could need for your questions, and an honestly overwhelming amount of extra races, classes, rules, and community made content. This sets it high above almost every other OSR game, in my opinion. 11/10. For the price point you have NO excuse not to pick up the library, and with the fact that he gives the PDFs away for free, you'd have to be literally insane not to download them immediately.
