Quick facts on EU from the official site:
Sauce;
http://www.planetcalypso.com/planet-calypso/entropia-universe/
so 810k, how many is active? who knows
This is why the 810k number is worthless;
I created 2 avatars PRIOR to creating my first avatar.... there were issues (won't go into them) with the first two, one of which was my own fault (randomed the look).
Since then I've started over with a new avatar.
That's 4 avatars from one person.
My best friend started EU... hated it, and stopped.
He came back, forgot his password, recreated, played for a day and quit, never to return.
That's 2 more registered accounts.
Now, consider all the people who join, get disenfranchised with EU and leave never to return. I'd speculate atleast half of newcomers never relog after their first few days.
Then consider all the users who've created avatars since EU started, but never stayed. I'd speculate atleast one third of all accounts were created by people who've since left EU, OR, don't login more than once every few months.
810k registered accounts, IMO (and speculatively), belong to approximately 300k different individuals.
Then consider the possibility that half those individuals were noobs who didn't stay more than a week.
Consider the possibility that half of the remainder are ex-patriots who've left for greener pasture.
That leaves approx 75k individuals.
Consider the possibility that half of those people log in once in a blue moon.
Now you're sitting around 37.5k accounts. Of these, I'd speculate that half REALLY play EU (10+ hours a week).
That's my opinion only, but, you can see how misleading the figures from MA can be to the outside world (or brooklyn) after a little bit of thought is put into the reality of the situation.
If the local bungy was to say "we had 300million visitors last year!" that does not mean 300million people bungy jumped.
ps: this is just playing with numbers I picked out of the air, there's as much fact in these numbers I've mentioned as there is in an MA press release.
