Don't worry, in this game no one can just run run and attack you. They have speciale events where players can fight eachother.

The gameplay is an advanced form of Lineage 2. You see all the monsters so you can avoid them at will. On some missions and quests, you will need some high level people to help you complete the mission or quest. You have "levels" that you can go through at will, but most levels you need to be a certain level before u atempt to cross them due to high level monsters. Im not the best at describing gameplay, sorry.
