Runes of Magic was terribly boring for me. Far too wow-like without enough reason to keep going. The novelty wore off too quick.
ATM, I'm trying Ether Saga (Open beta JUST released like a couple days ago or so) and its been very entertaining.
Time and time again, you hear people saying Pokemon should be an mmo, etc. Well guess what? Ether Saga is a Pokemon-esque MMO. EVERY class gets to have a pet, and can pick ANY pet type. Nobody is excluded. You can buy or capture more pets, and can trade them. (Sound familiar)?
IN addition, you can fuse with pets in your inventory, to share their power and you can also find card drops to TRANSFORM into various animals found in the game.
For a Free-to-play game, i gotta say its been worth trying.
