RebirthRO, a good private server. It's basically identical to iRO (the official English server that isn't free and therefore sucks balls), but the translation seems to be slightly better and they've added a lot of convenient features, such as the job changer and free warping NPCs. The client gives you access to a mid rate (100/100/20) server and a low rate (5/5/3) server. I played (don't anymore, but I might if I had people to play with) on the mid rate server because I don't like investing a few dozen hours to reach my 2nd job, but it still takes quite a while to reach the maximum transcendant level (255/120, I believe) if you're a person who enjoys grinding. My point is that a lot of people definitely still play the game, so don't let that scare you off if you're interested in trying it out.
