Disgaea: Afternoon of Darkness Gameplay 02 (Item World)

Every Disgaea has a "please level up this item to continue" point in the plot. To do that, you visit the Item World, where you apparently enter the world inside of an item, represented by randomized layouts filled with random inhabitants. Today, we're going to floor 10 as per the plot demands!
When I played the Disgaea 5 demo years ago, I put 30 hours in it, most of which was Item World. So, how does this iteration compare?
