Acquisitions Inc Series - Popular D&D campaign streamed on YouTube. DMed by D&D's lead story designer. Short episodes (~30 minutes each).
Critical Role - Another popular D&D campaign streamed on YouTube. These episodes are standard session length (3-4 hours).
D&D Beyond - The official digital toolset for use with the D&D 5th edition (aka D&D 5e) rules. I'll pay for the subscription (which unlocks content for all of us) if we decide to continue playing beyond this first campaign.
