• Medium: Few weeks of regular sessions.
• Long: Months of weekly sessions.

Life Factors

• Busy with work or kids: Short sessions preferred.
• Flexible schedule: Medium or long.

Hybrid Approach

You can play multiple campaigns:

• One long-term campaign for deep engagement.
• Several one-shots for variety.
• Sandbox campaigns for open-ended play.

The Endlessness supports multiple campaigns simultaneously (paid tiers).

Session Length vs. Campaign Length

• Session length: How long a single play session is (30 min to 4 hours).
• Campaign length: How long the whole campaign is (1 session to 100+).

They interact. A campaign with 30-min sessions needs more sessions to complete.
