I used to play Lineage 2 back around its release date. It was a lot of fun. Unfortunately I tried going back to it a while back and found it incredibly boring all by myself. Most of the players are already level capped and in uber gear. So you're mostly going through the game solo unless you find some people to go in it with you.
But despite that, I had some of the most fun playing Lineage 2. The zones were beautiful and varied, the music was really great, and the fishing was absolutely great! I used to fish quite a bit in the game, definitely try it out.
All of the races have unique classes, so it might take you a while to figure out what you want to play. The ranger class is a lot of fun, as well as the dwarf class (I forget what they're called).
I posted this earlier in another thread, but I love the log in screens for this game.
