Well I've never played City of Heroes before, but I like the concept of it. I couldn't find any p. servers on it though =/

Does anyone know if there is a game out there that has similar properties of that of City of Heroes/Villians?

What I like:
-Has to be f2p
-Pretty good graphics if its 3D
-I don't mind a 2D sidescroller
-Skill customization(Like CoH)
-Pets are a huge plus
-Not a crazy grind(I don't mind grind though)

If you need any clarifications, ask away.

Maybe try Flyff, i know it has pets and as i remeber it not a big grind.

Ragnarok Online has lot of skills, has pets, some grind ... unless high rate pserv XD graphics are somewhere between 2D and 3D

Flyff is pretty much super grind. I can't really think of any games similar to COH, I'm trying to find some myself 'cause my account expired 7 days ago.
