it doesn't need much net like I said
and there are always events ingame made according to occasions
for example
on christmas, all the players above level 35 got a free prenium gift
my gifts sucked though
on valentines day, creeps drop gifts, for male characters it drops girlish gifts, and for females it drops guy stuff hehe that is to kinda force characters to gift each others
on halloween, the sky turned dark, and ghosts starting creeping around town, and players started shooting fireworks
it was cool
and there is a weekly fishing event, ox event(an event where they test your knowledge, they start asking a set of questions, real life stuff, and if you answer everything right, you win something) there is a nationnal war event(never participated in it, not sure how that works)
it is quite nice
