I voted Old-School Essentials. It does everything I want an old-school game to do and none of what I don’t. The OSE Advanced Fantasy rules are a great synthesis of B/X and AD&D.
You can get the main book for OSE Classic for $1 in this Humble Bundle. You can get the Advanced books for a bit more. The modules are amazing. And so is the 3rd-party support.
Our latest role-playing book bundle features Old-School Essentials Classic and Advanced Fantasy rulebooks, plus campaigns, adventures and more. Pay what you want & support Children's Miracle Network Hospitals!
