They are about to get the iTOS trading patch tomorrow,
I don’t know what do you mean by ‘restrictions’ , if you can elaborate more please.
Yes, anyone can make an account at nexon & DL the game.
However, the account needs to be verified in order to play the game.
You will need a korean mobile number to confirm your identity as it is connected to your SSN. ( or get parents permission if you are under-age) I’d probably be against it unless you’re a citizen yourself or have a long-time friend.
They have a few more maps than iTOS,
Currently have more costumes/hairstyle than iTOS which in turn means, larger TP Store. They also have region specific class balancing at this time, so their classes are buffed / nerfed differently than iTOS ( at the moment, they have had a lot of buffs to some class dmg ).
This isn’t true. It was a thing, back in the korean test server but it was removed prior to the game initializing open beta in Korea. Korea has the same market system as we do, using silver & commision fee.
