RO is a great game, and all private servers are illegal. Dont waste your time playing some knock-off version of the game (private servers) when you can experience the real thing that started it all. If you want stability, play on iRO. You will NEVER have to worry about your account getting deleted/server wipes or any BS like that. Best of all its free! I used to p2p back in the day, so this is gold.
