Success or failure? Fantastic finesse or frustrating foul-up? Traveller has come a long way from the days of "Roll 8+ on 2D to succeed", but no method of adjudicating actions is perfect. This section discusses some of the ways that referees have gone above and beyond the standard rules for action adjudication.
- Glenn Grant's 'D66' Task System (Glen Grant) An extensible task system for T4.
- Ken Bearden's Alternative Task System for Traveller (Ken Bearden) A task system that balances skill and characteristic while maintaining the T4 task system's simplicity.
- An Alternate Task System For Traveller (Matt Stevens) A task system that avoids the 'half-die' of T4 and increases the importance of skill.
- System 1123: A Task System for Traveller (Ken Bearden) A dynamic task system that takes into account both skill and characteristic to require the player to make choices about how to approach a task.
