:\ erm... you just answered your own question.

But to give a more defined response then these are the events I remember it may not be all but I'm sure some people will add to the list of what they remember or know of;

December, Christmas - collect 3 bells get a Christmas sock filled with random Christmas related items.

November, Thanksgiving - Originally you get a pie filled with items, but since a few years ago they updated it to give you a pie and a turkey. Hand in both to the old lady in Kelan (where you get your tent from) and she gives you a box filled with random stuff OR you can just keep the turkey and open that instead for random stuff.

February, Valentines - collect cocoa beans and make valentines using the coconut basin for your pets or friends.

March, White day, get box with random drops. (no longer does this event)

May, Children's day - get a box or bag filled with random stuff (I have not seen this event in a long time, so I'm guessing they stopped)

June, Chinese new years/ Dragon boat - Get a box filled with fire works and random gifts. (I think they stopped this event as well)

March/April, WLO Anniversary - get a box or bag or gift box filled with random stuff. (seems like they also stopped this event)

October, Halloween - collect pumpkin seeds use the turf to grow pumpkin and smash them open for random stuff

January, New Years - get box or bag filled with fireworks and random items.

There should be a couple more.. but they've not in game anymore. Most of it is only for the Asian version so they stopped doing them in the English version. I once saw a website with some of the Asian event items and I was like "wow so lucky" cause their event get clothes and gear in some of the item drops like fans and kimonos and other stuff similar to how we have the Christmas clothes or hat with the Christmas sock.

Aniways~ those are the ones that I remember or still saw when I used to play the game.

There was and sometimes still are GM related events like item drops, or pk, or hide and seek, or racing, or manufacture and trade, or Q and A, or who is the strongest, or enter my tent, and etc... but they hardly seem to be any GMs around like there used to be. Originally it was about 3 GMs per server but now its 1 or 2 for the whole game. :\ so yea this game is dying and there are a lot of thing they no longer do. That plus players are often rude to the GMs and abuse and bullied them so they started to do less and less events. People always seem to find a way to ruin things for others -.- I was around for many of the events and was shocked to see how some players treated some GMs. Even my Ex and his friends were one of the types who'd PK a GM and say crap to them... *sigh* people can be so rude.

Most things these days is all about money.. then again its ALWAYS been about money with IGG, but now more than before after the company got sold.
