Fig. 2. Four snapshots of two harvesting strategies by two different types of participants in a hypothetical situation of a 5x5 resource, where resource units are depicted by star-shape objects. On the top row in the figure above, the participant moves his/her avatar (circle) eight steps per time period. There is almost no time for regeneration, and a participant following this strategy overharvests the resource by the fourth snapshot. On the bottom row, the participant moves his/her avatar only four steps per time step, and the resource has time to regenerate because enough tokens remain. After four time steps, the resource has not significantly declined, and a participant following this strategy can continue to harvest for many more time steps.
