I felt the need to comment on this thread as I've been playing ever since global beta back in 2005 with many breaks since then but the best gaming memories come from here.
I'll list quite a few things I remember from the early times, I was never a hardcore player so even if I played the whole 2005-2008 I never reached lvl 120 before 2009.
There are some things people may have pointed out already.
-Everybody remembers the starting island, the excitement of starting a new journey, screwing up stats trying to make a dexless sin or a sin-dit (which I never understood)
-You remember queuing up for Kerning PQ where Lakelis (the damn strict woman) who only let 1 party inside at a time. I still have the piece of paper where I wrote the names of people I had a lead on.. /find TigaaSin, xxxDexLessxxx
-The old maps, the annoying Jr.Boogies you could never hit and your journey deep inside Sleepywood dungeons at lvl 20.. The first huge task of collecting Cursed Amulets from Zombie mushies.. The Jr.Neckie quest which you got at lvl 15 but couldn't finish until 30s as #1 Their agility was too high 2# you could never find enough of them. And what about 1000 cursed dolls..? Great.
-The first Zakum helmet!! Everybody was crazy and he was like a god for many..
-The amazing wild boar grinding spot at perion.
-The super cool high leveld (70s) mages killing rogs on way to Orbis..
-The perion 'people's market' during the early days.. I still have screenshots lurking in some of my old cds, I will post them here If I can find them..
-And even though the world used to be just a small fragment of what it is now, it felt huge.. much bigger than it is now.
-What about all the friends you had, the amount of grinding, hene h0aring..
-Then Ludibrium came, a whole new world to explore! Tiger was popular but later found out he was a hacker, such a shame

-The (holy c*ap) amount of people at LPQ.. and how everything you did in the world felt much greater than it does now. Nothing feels the same but the game is still addicting as hell so the developers have done something right..
I probably forgot a lots of things already but it's nice to have a nostalgic journey every now and then!
I'm currently staying in Seoul and it's wonderful to see all the maplestory ads and how big the community still is in Asia, I'm changing to KMS this fall as the amount of people in GMS/EMS is decreasing and the publishers keep pissing people off.
