Haven't played Rengoku, but Untold Legends is pretty good. It's more of a western-style action-RPG. I.E. You create your character out of a base class, the objects you pick up from monsters take up space (you can only carry so much, the bigger the object the more room it takes off of your inventory, etc), certain weapons/armor/objects don't work for your base class, etc.
I wasn't expecting much from reviews but after some recomendations from people on here I decided to pick it up.
