his is called Ragnarok. Some people think you have to pay for the game, or maybe confused about setting it up. Its a preety fun, online roleplaying game. The server is play is free, and its fair/fun. If you are interested check this link www.s6.invisionfree.com/eternalro You have to register, and then download the files.
dont like eRO you should tried excalibur RO is was pretty popular back a year ago, but the server is still running, and theres not a lot of ppl but a decent amount throughout the day, especially durign the summer so it wont lag with the whole mass of players coming in so yeah
