I'm actually quite tired of hearing how they have a "small team". You make money off Item Mall, hire more people.
but see: how many people buy each months item mall points?
how many dollars do u think they earn?
20.000 dollar? more or less?
a good developer costs like 5000$ or more each month (ok, the rose developers are not the best ;-))
but, even if they have like 4 developers, 2 community managers and some gms the game would cost more than they earn (not to forget the costs for the servers which crash each day 1-2 times)
that means, that the rose developers develop for other games, too
that means also, that the community managers manage other communitys, too
and so on
at all i think, this team spends like 20% of their time for rose
