Aion wasn't grindy enough for you? Good thing NCsoft is now offering a two week free trial for their six year old MMO Lineage II: The Chaotic Chronicle then! The trial allows you to play three characters all the way to level 40, if you manage to make it that far in such a short time. If you do, please send us screenshots so we can gawk at your impressive grinding skills. Also, send us a picture of your eyes, so we can see what a person who hasn't slept in two weeks looks like.
Anyway, the trial is up for grabs at the official Lineage II-site. I wonder if I should give the game another go, perhaps the Dark Elves have learned to stand up straight by now...
