Like OSR style games but hate choosing classes? Come play KNAVE!
https://www.drivethrurpg.com/product/250888/Knave
No classes. Every PC is a Knave, a tomb-raiding, adventure-seeking ne’er-do-well who wields a spell book just as easily as a blade. This is an ideal system for players who like to switch up their character’s focus from time to time and don’t like being pigeonholed. A PC’s role in the party is determined largely by the equipment they carry.
Your goal is to go from poor commoner to a landed knight by going on dangerous adventures and finding magical items and loot. Go big or die trying.
