Same thing here. I first started playing shortly after beta until potentials came out, then quit because of the P2W factor was too much for me.
Then I came back for Reboot and had fun, but life was taking up too much time for me to have to spend hours grinding to get anywhere.
But now I don't have a job, can't go anywhere, don't need to leave the house, so back to Maplestory! So far I've levelled my main from 140 to 190, levelled a side account to 150 as a Kishin mule, and levelled multiple link skill classes to 140.
I've also spent a great deal learning about everything that's changed since I last played. I am so out of touch with this game, most of my time is spent trying to catch up. I have embarrassingly low range on my main, but it's getting better every day!
