Returning to the original topic...
I've just done the numbers again. This time, over the preceding 60 days, Dwilight saw an almost 20% increase in registrations. FEI and ATamara had 9% and 8%. Others were around 5ish% registration growth.
The story is slightly different for active players, though more optimistic than previously. While EC continues to hemorrhage active players (had 500 at my earliest numbers, now has about 405), Atamara seems to have slowed its decline (though it too has lost almost 100 active players since April). Moreover, activity has shown a slight increase in Beluaterra and Dwilight. Those two continents have displayed some consistent strength and seem to be getting stronger. No doubt at least part of Dwilight's strength comes from its high growth in registration. It is actually disappointing that its almost 20% in registration growth has led to barely 5% growth in activity. But better some growth than none.
FEI had a decline in active players that can be 100% explained by the recent multi-sweep. Without that sweep, FEI probably would have continued to show growth.
In sum: as per the usual, Atamara and East Continent are failures, while Beluaterra, Dwilight, and FEI are successes.
