Rose online, Gate to heavens, Ragnarok online All very cool games. ROSE is like no MMO that I've seen. I've been playing Ragnarok for like 4 years, and GTH is just weirded!
ROSE and GTH are still in beta so its free, Ragnarok still has 30 day trials. If you're bored of Star Wars Galaxies, Everquest and Lineage, check em out!
