I would also recommend Final Fantasy Tactics, one of my favorite games ever. It's actually not all that similar to the other FF games at all, save for maybe the job change mechanic.
Tactics Orge:Let us Cling Together is freakin awesome! Really well made and thanks to the branching storylines it has a lot of replay value. I would definitely at least try it out.
Hmm, it's not really an RPG but perhaps Monster Hunter might interest you? Killing enemies in order to craft better equipment is pretty addictive and the weapon variety is pretty good, lots of fun to be had trying out different weapon types.
