My best friend (after Vagus) has asked me to join a 5th ed D&D campaign. Problem is that the last time I played D&D was in the 80's. I've played other tabletop RPGs in the intervening years, but I'm very far out of the groove on D&D.
Does anybody know of a resource to prep me for the upgrade? Something a bit more concise than reading the whole Player's Handbook?
