please try NEXIA...
but srsly, though the graphics are simple, the amount of quests and things to do is more advanced than RO... RO really killed off a good game...
might wanna try Lineage II. I haven't really played it, but i played Lineage I for 2 weeks way back when and i must say the diversity of the gaming experience was amazing to me. I heard Lineage II has better graphics and more things to do, so i think it will be good... I stopped because it was P2P...
anyway, most MMOs out there seem to have the same general algorithms, do some quests, bash enemies, and that's it... WOW is no exception, other than more PVP-oriented gameplay/arenas (which has also been available in older MMOs) i don't see anything special in WOW...
imho we need more diversity and depth rather than just graphics, so yah perhaps Nexia and Lineage could be a good choice...
HON is good looking, but imho it's just an eye candy version of DoTA without really putting anything new on the plate. Gameplay dynamics remain the same and their attempt to put more emphasis on teamwork has (imho) failed...
there is supposedly another spin off from DoTA which promises more goals than just mindless bashing, but i have no access to it, so i never tried it... oh yeah, the name is Leage of Legends... LOL...
