The World 2-D was a MMORPG for computer systems and mainly worked on Windows 2000/XP. Players could log into the game when the server was online and interact with other people. Some popular activities on The World were to chat, level up by battling monsters, explore fields, or participate in events. Simply selecting the text and then placing it into a Word Document could save chat logs. There were five different root towns: Delta (1), Theta (10), Lambda (25), Sigma (40), Omega (50), and Phi (Crystal Castle Pass). However, each root town had a level restriction, so Players could not reach those locations until their level was above the required amount. The Phi Server was added in 2008, and Players had to obtain a pass from the Crystal Palace in order to visit. Delta was open to all Players
