Just creating an issue on this, since the system doesn't currently correctly implement DiS' intitiative system. While my coding skills are near non-existent, I would guess a full implementation would require extensive rework of the Combat Tracker.
Currently, it just seems to roll an unmodified d6 for everyone.
The correct system would require a kind of dialogue at end-of-turn, asking "whose turn next?". This dialog should keep track of round number and who's acted so far in a given round, correspondingly giving fewer and fewer available choices in a round.
