Is there a way to check when EXACTLY you started playing the game?

You can try to remember what boss was the last boss of main quest at the time. Someone might be able to pin point a time frame (like I came at 65cap, Ooze was last boss. That was September of 2015, but. I still haven't deleted my first friend so I know the day xD). And you can figure out the exact day from that maybe

 

But as a beginner, you would normally take some time to figure out how the game works and get equipment before you reach the final boss

 

Nope I complete the mq in one week when first I played toram online the last boss is mozto and the day was 18th of DEC when I start I don't even get a single thing I mean what the hell happen here.I am mage and distribute the state point like 10 dex 10 str 10 int 10vit 10critic 10 agi lololol
I am hell weak someone tell me to farm minotaur for spins but I am too happy when sololo give me spina like 10S 1S for animal skin.Then one kind Girl give a staff +5% int +5% matk pathetic stats right but its like grecia xtal for me.first thing I do is lock that staff so i won't be able to discard it even by mistake use mercy play 14 hours in a day hard to find ways in first time still somehow I complete mq with help of a friend and mery.then when I got info about stats skill points fill stats different type of bs i feel like damn this game gonna take a year.Now I am here its almost 4 months I think.
Its good I remember the date

 

For me, I think I started around when pg is the final boss, but then I fiddled here and there and only reached the final boss when it is Nurethoth

 

It's one way to figure out a time frame xD yeah you don't just go straight through story all the time, but sometimes you can just tell and remember. And thinking of the "strong" players and what gear they had. You may not have understood it then, but --hopefully-- it'll make sense now.

I remember Ooze gear everywhere. I remember lvling at Ooze. I remember people complaining about Ooze. I remember Ooze. I guess it changed later on that the final boss wasn't prominently flaunted everywhere like a poster board.

 

Those stronger players at my time normally wears killer coat, forest wolf garb, magic crystal armour or aqua garb I think XD damn nostalgia

 

So you came around the same time as OP, give or take a few months xD weapons are usually more of a way to remember. People change their weapons more than armor.

 

If I recall correctly, popular weapons at my time are sword of sin, empress bg and the dragon head staff (kind of forgot the name)
