what's the best online game that you played?

I like watching Ragnarok when my cousin used to played that game a lot, but i did not try to play, thinking that i started too late because he is a high level player already. So i played the Monster MU and get hook to it because I earned a lot from it selling items among children who wanted to level up. Funny thing is I trusted someone and shared my password promising me that he will provide me rare items when I played at daytime in exchange of making my character a killer. Indeed it work and increase my earnings.

well..i have heard one of my friend saying about this ragnarok..but i never played it though,....the best online game i ever played is counter strike..... i am also member of some dedicated servers.....i love that game...
