In D6, you're playing the role of players playing a role-playing game. That boat you needed? It's already in the harbor. That pit? It's already been dug. Every adventure will be different, but your objectives will remain the same.
Collect the bounties. Kill the monsters. Gain the glory. The most glorious hero will prevail!
The game is primarily competitive. However, the rulebook includes solo, co-op, and 2-vs-2 team modes.
