Most aspects of it feel like Dark Cloud than Minecraft, tbh, besides the actual block parts. Creating things to the specifications of the NPCs and all that.
That being said, the aspects that ARE similar to Minecraft have the helpful polish of a AAA company. Only issue I can foresee at the moment is a potentially unwieldy camera, especially in tight, indoor areas.
Other than that, lots of fun, music was really good...demo went a long way towards pushing it up my "to buy" list.
